THE WEATHER IS ALWAYS FINE PEOPLE ARE ALWAYS FORTUNATE
What the hell are you doing?
Are you plotting against Yaning?
What are you talking about?
How could I be plotting against her?
Nothing is off limits to you.
You still have the mentality of one involved in class struggle.
You need to relax.
What kind of person do you think I am? Replacing people as I please?
-You're being silly. -Not exactly.
You know he's getting a promotion.
Do I not know you well?
Even if he's promoted to be the political commissar,
he still needs to be suitable for Yaning.
Is there even a question of whether he's suitable for her, huh?
If he's suitable for Yafei, why wouldn't he be suitable for Yaning?
What exactly do you mean? Enlighten me.
You don't have the acumen to understand the logic behind it.
What do you know?
You only know to replace someone when that person doesn't suit your needs.
Can you simply replace in this case?
Will you ever get it?
What kind of logic is that? It's nonsensical.
When is he getting a promotion?
See? I told you.
I'm playing with you.
Are you Director Meng?
Yes, I'm Meng Tianzhu
This is...
Your mother asked me to bring you this. Please verify its contents.
I don't need to check. It's just a sweater.
Thank you for the trust.
You smile like your sister.
You've met my sister?
Not only have I met her, I pursued her.
But I wasn't successful.
So, I almost became your brother-in-law.
But it was an "unsuccessful attempt."
Have you told your parents?
I just mailed the letter yesterday.
What are you laughing about?
I'm laughing because there's going to be a "big earthquake" in your family.
How can you be so happy about an impending calamity in our family?
I am both happy... and worried.
I am happy because your family will be distracted.
I'm worried because I am afraid... I won't be accepted by your family.
Do you think you can earn their trust?
Who knows?
I'm not sure.
"Department of Literature, Shandong University."
Let me see first.
Bossy! Why do you have to be the one to read everything first?
Well, I'm her mother.
I have earned the right.
By being the person who gave us life and brought us up.
It's your turn, Big Cat.
Pass.
What does the letter say?
Has something happened to Yaning?
The letter says that
your little daughter... is dating Director Meng.
Mom...
That Director will become my brother-in-law?
You sure are happy about him becoming your brother-in-law, aren't you?
An Jie, you're being unreasonable.
You insisted that he and I should be introduced.
So now he may become your son-in-law, shouldn't you be happy about it?
I think he's suitable for you, but not necessarily for Yaning.
Well then, we should talk this over.
Now why is that? What is your rationale?
I'll explain it to you.
Mom means to say...
You have a knack for public service. So, you are perfect for Director Meng.
Your sister is a literary writer. She's not suitable for Director Meng.
-Is that what you mean? -Exactly.
-Congratulations. -Uncle.
-There will be a wedding banquet soon. -Why is that?
Yaning wrote. She said she's dating someone.
That someone is Director Meng, the political commissar.
-Political commissar? -Didn't you know?
Director Meng just received the order.
The 29th commissar. He'll start right away when he gets back.
-You see, Yafei? -Really?
Commissar Meng should have been yours. What a shame.
Nonsense.
Yafei rejected him, and Yaning took over. It doesn't make much difference.
Come, have a seat. Sit here.
Look at you. All of you are obsessed with public servants.
You'll see. You'll regret it someday.
I won't regret it.
We shall see.
All right. We shall see.
Why are looking at me like that?
Look at you. Your mannerisms are those of the working class now.
You don't look like a capitalist's daughter anymore.
What should a wealthy man's daughter look like?
I'm not sure, but she certainly wouldn't look like a peasant.
Silly child, that's a rude thing to say about peasant women.
-Come on, let's play. -Let's play.
THE 90s
Hey, where did you put the thermometer?
Hey.
Jiang. Where did you put the thermometer?
Jiang.
Where did you put the thermometer?
How annoying. She never stops yelling.
Jiang.
Are you deaf? Something stuck in your ears?
What are doing yelling like a mad vixen?
I'm like a vixen? And what about you?
You're like a penny-pinching landlord.
A capitalist.
You are like a parasite that feeds off me.
Man, you sure are argumentative.
You always have to have the last word.
Why is she always crying?
Do you think she has a fever? Where is the thermometer?
A fever?
Let me check, let me check.
She's not hot.
Is your hand a thermometer, too? Go get me the thermometer.
Okay, Yaya, good girl.
Grandpa is looking for the thermometer. Don't cry now.
Here it is.
What is going on with you?
-You just won't stop crying. -Is she crying because she's not well?
Is she not well?
-How would I know? -If you don't know, don't say anything.
Go downstairs and fetch some water for her.
You were just downstairs. Why didn't you get her some water?
I was busy looking for the thermometer. It didn't occur to me.
Are you going or not?
Okay, I'll go. I didn't say I wasn't going to get water.
Yaya, Yaya, are you thirsty?
Grandpa is getting you some water.
Let me see.
You don't have a fever.
You're okay. No fever.
Here you are.
It's too hot.
I tried it. It's fine.
It's fine for you, but not for her.
Is a baby's heat tolerance the same as that of an adult?
It's fine for her to drink. Why don't you try it?
Dirty looks won't solve anything. Drink it later, then.
Don't cry, Yaya, don't cry.
Did you discipline her?
Why would I do that? I'm not her step grandmother.
You're upset because I've been a slacker. I know you.
Then why don't you make yourself useful?
Wasn't it your idea to help take care of the kid?
And you've been sitting around, not helping out.
You take all the credit,
while I do all the work.
Okay, stop it, stop it.
I'll put some cold water in it, all right?
You don't have to bring that up every time we argue.
Here.
Open it.
You're so dumb. Grandma will give you some water. Let me check the temperature.
What a hard life I have!
I still need to work like an old maid at this old age.
What's the point of life anyway?
What... is your problem?
Taking care of grandchildren and your husband, cooking...
Aren't these the most enjoyable days for a woman?
-You're taking your life for granted. -Says who?
Teacher Ge, for example, is truly enjoying her life.
Is that so?
She spends her life as someone's second wife.
She doesn't even have children.
Is that the most desirable lifestyle for a woman?
Look at her.
She lives a healthy and free lifestyle.
She practices dance and martial arts daily.
Look at me. All I do is take care of a baby and cook.
Just like an old maid.
It's obvious which one of us is enjoying her life.
PEOPLE'S DAILY
Auntie Chen, please turn off the music. I have an announcement to make.
It'll only take a minute.
Uncle Zhang, please turn off the music. I have an announcement to make.
Uncles and aunties, could you give me five minutes of your time?
-I need to say something, all right? -Please turn off the stereo.
Go ahead and say it.
It's good news. I only bring good news.
Army Day is coming, right?
We're going to hold a social dance contest between all of the sanatoriums.
Each office will have ten attendees. There will be 20 teams altogether.
Everybody, get some practice.
The day after tomorrow, we'll have an elimination contest.
You're all very welcome to participate to win honor for your respective sanatoriums.
-Yes, yes. -All right.
Hey, Yafei, you should ask your mom to participate in the contest.
-She'll be a great help. -That's right.
In our sanatorium, no one dances better than your mom.
Back in the day, your mom was a terrific dancer.
She even danced with Soviet Union experts.
Is that right? How come I didn't know about it?
Yafei, you weren't born then. Go ask your dad. He knows.
Sure, I'll ask my dad. You guys carry on.
-Okay, okay. -All right.
Auntie, let's go home.
Wang, here, here.
I'm leaving.
It's wonderful... that all of you get either to dance, or practice sword dance,
or practice calligraphy at home.
Unlike my parents, who don't go out anymore.
There are times we don't go out either.
It's your mom's turn to stay home.
It was me who brought up you kids.
It's your mom's turn to experience child-rearing.
While it's dark in the east, it's bright in the west, right?
What does that mean?
It means it's my mom's turn to experience a hard life, right?
Bringing up one's own children cannot be referred to as a hard life.
If you're stuck at home, busy with housework,
would you call that a hard life or an easy life?
I wouldn't call it an easy life, but it's not a hard life either.
Neither nor, what is it then?
I have no idea, but it's certainly not a hard life.
-I'd better get going, Auntie. -Go.
Yafei, come over here for a second.
Uncle, any orders from you, the chief?
I don't have any orders for you.
Just move all your old newspapers from your office to my house.
Are you selling old newspapers?
Selling them? I'm using them to practice calligraphy.
Didn't I just buy you some rice paper for calligraphy?
He's saving it, and uses newspaper instead.
Great. This means... no need to buy more rice paper.
There are tons of old newspapers for you. Take as many as you want, all right?
Big mouth.
You see, Yafei? Your uncle is upset.
You must continue to buy rice paper, and give him newspapers too.
-You hear? -No problem, Auntie.
You're not using the rice paper as hand towels, are you?
I have to go, I have to go. I'll buy more rice paper.
Bye, Auntie.
Don't cry.
Mom, where's Dad?
Out buying bread.
Why is she always crying?
Look who's talking. You cried a lot as a baby too.
Okay, give her here. I'll hold her, I'll hold her.
Don't cry, don't cry. It's okay, it's okay.
-Good girl. Don't cry. -Don't cry.
Seriously, I told you to get a nanny, but you wouldn't.
I wanted to pay for the nanny, but you refused my offer.
I don't understand what it is with you guys.
I wanted to hire a nanny, but your dad wouldn't let me.
We were afraid of gossip if we hired a nanny.
Who would do that?
Dad is still living in his past as a commander.
He thinks people are still watching his every move.
No one knows who he is.
Do you know who I am?
Baby, Grandpa's home.
Here, have some warm hugs from grandpa.
Okay, no crying now.
Why are you crying? Are you hungry?
She's just had her bottle.
Is she not well, then?
Dehua said her dad cried a lot too, when he was a baby.
It runs in the family.
Nonsense.
Using genetics as an excuse. I say those doctors don't know anything.
Nonsense.
All right, get out of here. You're so annoying. The food will be ready soon.
No more crying.
Mom, have a seat. I have to tell you something.
If I could sit, I would've already sat with you.
I don't need you to remind me.
Just try sitting down.
Darn it.
Okay, okay.
It's okay, it's okay.
Well, you asked for it.
Well that's because we owe it to her dad
Some of his cohorts are in the military, while others are at university.
Only her dad is stuck in his hometown, going up and down the mountains.
He is now doing hard labor there.
What's wrong with working as a laborer? Blue collar workers spearhead everything.
Shut up.
We should have sent you to a rural area to work then.
Real gold will shine, no matter where it ends up.
If I had gone to work the fields, I would've become wealthy by now.
Unlike him, I would have been able to support my child.
You're being boastful. You're just bluffing.
You're not even married.
You're getting old, someone no man would want to marry.
Don't try to convince me. It won't work.
I refuse to meet that guy. Just forget it,
Okay, fine. It's best you two never meet.
I wouldn't have to deal with the embarrassment, in case you were rejected.
Stop arguing. Eat up. I'm hungry, too.
What are you looking at me for? It's too early for me to get married.
-Besides, I don't owe his dad any favors. -You and her dad are twins.
You've had all the good luck in your life.
You owe him because he's not been as lucky as you.
Sorry. That's fate.
I have no control over fate.
Are you done eating? Help mom with the baby.
I need to talk to her.
What is it? Give me the baby.
That's between us. You don't need to know.
Well, who cares?
Why don't you use a towel to dry your hands? What a waste.
Fine. I'll recycle it later. I'll use it to wipe my mouth.
Dad.
Please give us some privacy, okay?
-We need to have a chat -Why should I leave, huh?
You leave. Talk somewhere else.
-What is it? -Huh?
I have an idea. Dad, come here.
Come here. Let's talk about it together.
All of the retired cadres will know about it eventually.
-Give the baby some water. -So I'll let you know beforehand.
On this year's Army Day,
all of the residents of the sanatoriums will hold a social dance contest.
-You must attend. -She's not going. She doesn't have time.
This baby is a handful.
How will she find the time to dance?
It's none of your business. I'm not inviting you.
-Your mom cannot attend. -Says who?
Says me. What are you going to do? No.
Would you like to take part?
All of the uncles and aunties have said
that if you participate, our sanatorium will win the contest.
What else did they say?
They said that when you were young, you danced very well.
Several Soviet Union experts fought to dance with you. Is that true?
-That's not the case. They lied. -I thought so.
Mom... I...
I just started working in culture promotion.
Don't let me fail at it.
Are you done yet?
Okay, I'm done, I'm done.
-Here. -Here.
Come to Grandma. Don't cry, Yaya, don't cry.
Look at me and the baby. I can't find time for the event.
I don't care, I don't care. You must think of something.
You're being unreasonable. Hurry up. Do the dishes after you're done.
Sure, no problem.
Mom, I'll do anything as long as you promise you'll do it.
Little mousy gets on the lamp
-Oops, oops, he falls down -Where is everyone?
I'm here, am I not?
I mean her grandma.
Where's her grandma?
-Am I not her grandma? -Stop playing around. Where's her grandma?
She went... dancing.
What are you doing here? Why are you looking after the baby?
Do you think I like this?
If it weren't for Yafei, I wouldn't want to be here.
But you're home. Wonderful. Please take over.
-Here's the baby. -Who's taking the baby?
You, you're taking the baby.
The baby should be returned to the person you received her from.
-Where are you going? -It's none of your business.
I know where you're going.
Hi, you're here.
Why? I am not welcome?
Of course you're welcome here. I'm surprised and excited that you came.
After all, we were educated by the communist party for years.
Please don't hold Mom back.
What's with the attitude?
Who's that guy?
He's an instructor from the cultural palace who we invited.
So what if he's an instructor?
Your mom is a better dancer than he is.
You're right. I agree. He doesn't dance all that well.
But what a shame.
What do you mean?
While my mom is a great dancer, we cannot find anyone in the sanatorium
whose dance skills can be paired with hers.
Who is she going to team up with?
-She's worried about it now. -What's there to be worried about?
I'll pair with her. I'll dance with her.
-You? -Yeah.
-Can you dance? -Why not? I've danced before, all right?
Don't bend so much.
Ouch!
Get away from me!
What is it?
What do you think?
Didn't you know you stepped on my foot?
I only stepped on it lightly.
Besides, I stepped on it with my bare foot.
Does that make stepping on my foot okay?
Your feet are as big and heavy as bear paws.
Besides, you stepped on my foot several times.
You're such as princess.
You can't take the slightest pain.
How will this complete the assignment that my daughter gave to me?
Get up. Let's carry on practicing. Come on.
-Let's carry on. -That's it for today.
One day of practice won't make you a dancer.
Besides... I'm tired.
Let me rest for a while.
One... two... three.
-Don't bend. Stand up straight. -Two... three.
One... two... three.
One... two.
She is exhausted.
Damn, what a princess.
Who gets so exhausted after a little dancing?
Fine.
Forget it.
What did she say?
She said she doesn't have time.
She needs to pickle some vegetables.
Does she have to do that now?
What are you yelling at me for? I dare you to yell in your sister's face.
I'll talk to her.
I think it's best that you don't. Do you think you have a thick enough skin?
You wouldn't be able to take the rejection.
I don't think Dehua is behind it.
-It has to be Ding. -Mm?
It's Ding who won't allow her to babysit the baby.
I'm sure of it.
So... Why doesn't Ding let her come here?
How would I know? I'm not Ding.
Answer... the phone.
Why don't you answer it?
It'll be your sister-in-law. I'm not going to answer it.
Why are you so sure?
Just answer... the phone.
Hello?
-It's for you. -Who is it?
Answer it, then you'll know.
What is your problem? You are being a pain in the butt.
Can I ask who this is, huh?
So if it was someone else, you wouldn't answer it?
I most definitely would answer it, if it were from someone else.
Shoot. What is it that you want?
-Tell him. -What...
What am I calling him for?
You're not becoming senile, are you?
Why am I calling him?
We want to ask if your sister can babysit the baby.
Hello?
There is something I want to discuss with you.
Army Day is coming, isn't it?
The sanatorium members are going to hold a dance contest.
We wanted to show our support, so we've signed up for the contest.
Well, that's a good thing.
-What is it? -There's nothing good about it.
So now we have a problem.
We have no one to look after our granddaughter.
That is indeed a problem.
Therefore, you also need to show your support.
-How are we going to do that? -You ask Dehua to come...
look after the baby.
She only needs to be here for two hours every day.
We need to practice before the contest. Would that be all right with you?
I'm fine with it.
But I won't be the one who looks after the baby.
The problem is, she can't do it.
She can't look after the baby.
She hurt her back.
When did that happen?
Yesterday.
Nonsense.
Didn't you say earlier that she had to pickle some vegetables?
She's being stubborn.
Of course, I won't let her.
He hung up.
You...
Why did you lie? I hurt my back?
I had to lie, so you wouldn't have to look after the baby.
You've spent your life looking after babies. Aren't you tired of it?
Aren't they in a contest?
Any other kind of contest would have been better. Why a dance contest?
Hugging and twirling in public at this ripe old age, have they no shame?
Don't they get vertigo?
You're... just... jealous.
Why would I be jealous of them?
They're being indulgent.
Damn.
Ridiculous.
I don't need his friendship. I don't need his help.
We all need friends who help us when we're in need.
I... have other friends too.
Uncle Yin, you guys need to speed up with your practices.
Uncle Zhang, you're getting better.
Auntie Wang is the best dancer here.
-How am I doing? -Great.
-Hi, Teacher Ge, Uncle Wang. -Yes.
-Yafei. -Huh?
Why have your parents stopped coming to practice? They need to be consistent.
-They are here, aren't they? -You need to stop looking for them.
Without her, I'm not as motivated. The others must feel the same.
Yafei, We need your mom here to boost morale.
Mom.
What happened to you guys? You only went to practice for two days.
Is this how you support my work?
We wanted to come.
But how? We have to look after the baby.
Where's my aunt? I thought she was coming to help.
She changed her mind.
She said she hurt her back. So she can't come.
Two...
Give me the baby.
-Yaya, Yaya, don't cry. -Yaya, don't cry.
Bad Grandma, bad Grandma.
Yafei is here.
Uncle, why did you change your mind?
Don't talk to me like that. I did not change my mind.
You agreed to help out with the baby. Why did you change your mind?
Your aunt hurt her back. She can't work.
Who's come to visit?
I heard someone talking. So, it's Yafei.
Why... Why are you looking at me like that?
Didn't you hurt your back?
And you can't work?
What are you looking at me like that for?
You, the honorable veteran cadre, lied as well?
So you can tell a lie, but I can't?
You are a national treasure for the Party and the people.
The Party and the people cherish you like a piece of treasure. Why, huh?
They certainly wouldn't appreciate someone who lies.
I didn't... lie to them.
A lie is a lie. It doesn't matter who you lie to.
Besides, by helping with the baby, you indirectly help the sanatorium.
That would be your contribution to the Party.
That's your duty as a retired cadre.
I'll tell you what.
Either you sign up for the dance contest,
or you stay home and watch the baby.
You can choose between the two.
We'll stay home and watch the baby.
Why do we have to choose to look after the baby?
What about those who didn't sign up for the contest?
Why do you insist on asking for our help?
Those other people are not my parents, nor are they my uncles and aunts.
Are they my family?
I don't mind if I don't receive support from non-family members.
Because I never give them anything, such as rice paper for calligraphy practice.
I see a difference there.
Look at my parents, huh? They'll do anything for me.
Look at my dad. He has no rhythm.
But he still tries his best to help out.
You two pretty much stay home and slack off.
That's not true.
Well, what about you pretending you're unwell?
What are you doing? This child. What are you doing?
I bought them for you. I'm taking them back.
You gave them to me. You can't take them back.
If you can change your mind, I can give them back.
Fine, fine. Put the rice paper back.
I thought you never used rice paper. Don't you use newspapers instead?
The old newspapers I brought you, did you sell them off?
-Nonsense. Give them to me. -Yafei, you are something else.
Only you can persuade your uncle.
So what?
So what if she can persuade me?
No one wants to marry her. She's useless.
Let's go.
Don't eat that.
Stop chewing on it.
One, two, three. One, two, three.
...four...
Ding is quite pissed.
Okay, twirl, turn around.
Okay. Turn around again.
You stepped on my foot.
Does it really hurt that much, huh?
-Would you like me to step on your foot? -Go ahead. Go ahead.
You're fine.
Get up, get up. Let's carry on with the practice.
If people want to keep their feet, they shouldn't dance with you.
Is it that serious? I only stepped on you once.
Only once?
Okay, fine. Several times, okay?
-Come on, let's carry on practicing. -I can't. My foot hurts.
You're being such a princess. Come on, come on.
You shouldn't give up because of a slight wound. Carry on!
Look. Yafei is looking at us. Come on, let's dance.
My dad isn't much help.
But he's quite motivated though.
That's why he makes it so hard for me.
Good thing your mom dances well at least.
He really pales in comparison, though.
Just... look at him.
He is a fly in the ointment.
No. I must do what's right.
What do you think?
Are you my mom?
Who else could I be?
I thought you were an angel, descended from heaven.
-I'm the angel's mom. -Holy mother?
Stop it.
Are your colleagues annoying you?
No. They sure do love being around me.
When they don't see me, they start to look for me immediately.
Don't be boastful.
Your dad's hypertension has gotten more serious because of the dancing.
He's been too excited and worried about the dance contest.
Can he dance? No, he doesn't have what it takes.
You are too good for him.
You should be paired with Teacher Ge or Uncle Wang.
They present themselves nicely.
But when I see you and dad...
What do you mean?
It's like looking at beauty and the beast.
I'll go check on the Jade Emperor.
-Dad. -Mm?
Dad, let me see.
This isn't going anywhere.
What do you mean?
-Come on, take it off. -Why? Don't you like it?
Not only do I not like it, you look horrible.
I thought this outfit was really bad.
But you wanted me to wear it.
Mom looks great in hers.
When I saw Mom, I thought we'd definitely win first place.
But now, after seeing you in your outfit, I'm not so sure.
Not bad.
-But of course. -I'm impressed.
I am glad you're impressed.
But the key is that the judges must be impressed as well.
If I'm impressed, the judges will be too.
In fact, I used to be in charge of art events when I was in the army.
I sang and I danced. I did everything.
No wonder. You look like someone who has talent.
So, you're a dance expert?
Not really.
Are you plotting something?
No, it's not what you think.
I want to ask if you could help us out before the contest commences.
Also, to confirm all of the contestants on the list.
Huh?
Are these all of them?
The requirement is ten pairs, but we have 12 pairs.
In case some become ill, we have extra teams standing by.
However, everyone has been extremely motivated.
Everyone is fine.
-So what are you going to do? -Well...
Elimination.
I see.
You want me to play the bad guy.
-Qi, did you get that? -Yeah.
-Let's go. -No, no, I need your help.
Finalize all of the contestants before you ask for our help.
Don't leave.
-Everyone, take a short break. -Huh?
Yafei, why did the commissar and sanatorium director leave?
They were annoyed by you.
How and why? What are you talking about?
Look at you. You can't dance.
Bend, bend.
You're no help to Mom at all.
Yafei...
are you trying to eliminate me?
Actually, I don't want to.
But I have no choice. Everyone has suggested it.
Who is everyone? Who? Huh?
The director, commissar, and everyone who works at the sanatorium.
Of course, we also asked for their opinion.
It was unanimous, wasn't it?
What did they say?
They said that you lack something.
Wh... Wh... What is it that I lack? Tell me.
Overall, something is missing.
Especially when paired with Mom, you two are simply...
uncoordinated.
What are you looking at me for? It's none of my business.
Nonsense.
Did you think I liked coming here to do this silly dance?
If it wasn't to support your work...
I wouldn't have agreed to be a part of this event.
I know. Thanks for your support, Dad. Thanks for understanding.
Understanding? I don't understand anything.
Hey!
-Where are you going? No. -Your dad is out. So, I am out too.
Don't make it worse.
I have high expectations of you.
-What expectations? -I want you to win first place.
What about your dad?
Don't worry about him. You focus on the contest.
I'll take care of Dad, okay?
-All right? -No, no.
Trust me. It's going to be okay.
You trust me, don't you?
What happened, Commander?
He must have been eliminated. Jiang Yafei is a tough cookie.
Aren't you hot?
Ridiculous, huh?
You have your own housework. But you're here to help with their housework.
I didn't even look after my own grandchildren.
Well, you shouldn't be talking about it.
Don't eat that.
Why are you home so early?
-What's wrong with him? -How would I know?
Let me go check on him.
He's sleeping.
What's wrong? Huh?
Aren't you feeling well, huh?
Scratch him. What happened? Are you all right?
Get out. I need to get some sleep.
I came to look after the baby to support you with the contest.
I didn't come to support you getting your beauty sleep.
You need some sleep? I need some sleep.
Here. Yaya is all yours.
I'm going home to get some sleep, too. Here's the baby.
What is the matter with you?
Get out. Get out!
What is the matter with you?
Let's go. Don't cry.
Shut the door.
What the hell?
Why am I being so nice?
Huh?
Don't cry, don't cry.
