Episode 2
My lord. We know why solar and lunar eclipses occur.
So why is it difficult to accurately estimate the dates and times...
for these phenomena?
Well, it's due to...
the irregular movements of the sun and the moon.
Their movements...
slow down as they move away from this terrestrial sphere...
and become faster as they move closer to it.
Especially in the case of the moon,
the change in its speed is quite drastic, which...
makes forecasting solar and lunar eclipses even more challenging.
My lord.
The lunar eclipse that will take place on this Thanksgiving.
I want to watch it with you.
Yeong Sil.
Yes, my lord.
My prediction for a lunar eclipse taking place on Thanksgiving Day...
could be wrong.
(A lunar eclipse: Earth's shadow blocks the sun's light.)
Look at the sky.
Astronomical phenomena are...
difficult to comprehend as we don't know where they start and end.
We cannot say that we fully understand astronomical movements...
just because we observe the sun and the moon.
My forecast for the lunar eclipse on this Thanksgiving could be wrong.
If...
my prediction is wrong, would you...
be able to find out...
the reason?
Yes.
I will be sure to do so.
(Three months later)
You, lazy brat.
You just started working here.
And you're already trying to slack off! How dare you.
Let me teach you a lesson today.
- You, little mouse. - You, jerk!
I told you that I'd hurt you...
if you bother my son again!
Goodness. Let go of me!
I can't do that.
If I let you go,
you'll pick on my son who is as precious as jade.
You'll shove his head in water again.
I cannot let you do that!
Let go of me! Push her. Push her away for me!
- Okay! - Yes!
- Go away. - Let go of him.
Gosh, let go of me.
Jerks. Let go of me!
Let me go!
Goodness. What did you say? Your son is as precious as jade?
He's a mere servant in the local civil court. What? Jade?
How dare you compare him to jade that symbolises the royal family?
You are absolutely out of your mind.
Why do you pick on my son? Why do you bother him so much?
You really don't know?
Your son...
will grow into an obnoxious jerk...
because of the noble blood in him.
So I need to tame him and train him properly from the get-go.
The noble blood in him...
I don't think your mum knows that...
she's making your life more difficult by acting that way.
I'm worried about you.
Would you be able to survive this and get married later?
With my training,
he'll be able to live a stable life as a servant here,
so you should be thanking me now.
Right.
That nobleman.
He promised you that he'd get you out of your low status...
then ran away overnight. Aren't I right?
- Poor you. - You.
You, jerk!
- Calm down. - Let's get her out of here.
- Let me go! - Okay, hold on.
- Gosh, seriously. - Goodness.
- Why are you doing that? - Gosh.
"Before you speak,"
"you must think..."
"about how you can speak as earnestly as possible."
"You must also remember..."
"to treat others respectfully and politely."
"Moreover,"
"you must not be afraid to ask when you have doubts."
"When matters aggravate you..."
"When you are enraged..."
Master Hee Je. I sprayed water evenly throughout the front yard.
- He's saying he finished the job. - How foolish.
Do you think that amount of water is enough to cool down the yard?
Did you hear? Did you hear what your master said?
Why are you just standing there? Go and bring more water.
Master Hee Je, I must deliver water to the forge too.
How rude! How dare you talk back to your master!
Hak Joo, wait.
Eun Bok. I am aware of your stupidity,
but you must at least know how to prioritise.
The blacksmith and the son of Dongrae-hyun's present governor.
Between these two people, whose order should you be prioritising?
Oh? The moon is visible in the afternoon sky.
Eun Bok. How can you be thinking about that now?
Eun Bok! What are you doing?
I told you that I need water at the forge. What are you doing now?
Goodness.
If this turns out to be nothing special, I'll be angry at you.
Pull it.
Wow.
Oh my.
I can see the stars very well lying down like this.
Suk Gu.
Focus and keep looking at the stars.
You'll see them moving.
They revolve around the North Star.
Oh?
I saw you with those when we went to the well to get water.
What are they for?
I observe the moon and record its movements.
The ones on top are the lord's observations.
The ones below his are my observations.
Your observations match those of the lord.
Yes. So far, our observations of the moon's movements...
match in terms of its location and the time.
- I see. - By the way, Suk Gu.
If my observations continue to match the lord's,
there will be a lunar eclipse on this Thanksgiving.
Did you say that...
the next lunar eclipse will occur a month after this Thanksgiving?
Yes, Your Majesty.
- Are you certain about that? - Yes, Your Majesty.
According to the Chinese astronomical calendar...
You are bringing up the Chinese astronomical calendar again.
Can we not be certain of any forecast without it?
(Yu Taek Sang, Chief Officer of Astrology)
(Lee Chun, Chief Officer of Police Agency)
(Hwang Hui, Secretary of National Defence)
Please answer, Lord Yu.
That is correct, Your Majesty.
As you are aware, the Emperor of Ming strictly forbids the kings...
of its sovereign countries from studying...
astronomical phenomena on their own.
Therefore, we should plan the lunar eclipse ceremony...
according to the Chinese astronomical calendar.
Having that excuse must put your mind at ease.
Let me ask you then.
Have you ever thought that it could be the Office of Astrology's duty...
to observe Joseon's sky to conduct its own lunar eclipse ceremony?
Your Majesty.
Why are you so surprised?
Joseon cannot have such attitude as one of Ming's sovereign countries.
Making that kind of remark could be considered disloyal.
I will decide what is loyal and disloyal!
Then how will you make up for your disloyal act?
Their calendar failed to forecast the last solar eclipse correctly.
You shouldn't be blaming me for my disloyalty now.
- Your Majesty. - Yu Taek Sang.
What do you think your most important duty is at the moment?
I must rush to the Office of Astrology...
and hire specialists who are skilled in arithmetic and astronomy to...
- predict solar and lunar... - Stop!
Your life depends on the accuracy of the forecast on this lunar eclipse.
- Your Majesty. - Your Majesty.
Are you nervous, Lee Bang Won? You must be well aware...
that your kingdom is like a castle built on sand.
Chun.
Yes, Your Majesty.
If the Office of Astrology predicts the lunar eclipse incorrectly,
we won't be able to hold the lunar eclipse ceremony once again.
Your Majesty.
If you are concerned...
because of your deceased siblings,
we could hold a Buddhist ritual to make sure they rest in peace.
Do you think I'm preoccupied with the ceremony...
because I'm concerned about my deceased siblings?
Chun, do you also think that I'm begging for gods' forgiveness...
because I am scared of ghosts and demons?
Your Majesty...
That is not the reason.
I'll have to face and deal with my siblings if they appear as ghosts.
I know what I have done to them.
- Your Majesty. - Your Majesty.
I want to hold a proper ceremony for one reason.
I want the people to be fond of me.
Joseon was founded less than 10 years ago.
It means that those who were born as Joseon's people...
are less than 10 years old.
Except for those children,
everyone used to belong to Goryeo.
Myself,
Chun and Sir Hwang, you too. We were all Goryeo's people.
To ensure that Goryeo's people...
can live happily as Joseon's people,
I need Heaven's will more than anything else.
What I am saying is that...
we need to hold a proper ceremony...
to show the people that the gods have approved the King of Joseon.
Your Majesty.
I hear that there will be no solar eclipses for several years.
We ought to make sure...
to hold a proper lunar eclipse ceremony. It must be done well.
Your Majesty.
When a solar eclipse wasn't seen from here, Suchang Palace that day,
it was seen from Dongrae-hyun.
What did you say?
What did you just say? There was a solar eclipse?
That's correct, Your Majesty.
However, that day...
Someone said that the eclipse would only be visible from Dongrae-hyun.
Who was that?
Who said that?
It was Jang Sung Hwee.
The man who doesn't support Joseon?
Why are you telling me this now?
He calculated...
when the lunar eclipse would be.
It will be on this Thanksgiving.
What?
The Office of Astrology said it would be on the next full moon.
Yes, Your Majesty.
Yu Taek Sang said...
it would fall on the following full moon.
Does Jang Sung Hwee...
have evidence to back up his forecast?
Yes.
He has been calculating the dates of solar and lunar eclipses...
differently from the royal astrologers'.
He has been observing our sky...
to make his forecasts.
I knew that...
he would be doing so.
Of course.
I know him well.
He hates me.
But I always knew...
he would be doing what I want the most.
He is heartless and cruel.
Your Majesty.
No one in my royal court...
can or will play the role that Sung Hwee could.
Lee Chun.
What should I do?
Should I just continue to follow...
the Chinese astronomical calendar...
and its forecasts that never seem accurate?
Is that the fate...
of my Joseon?
As you said, my lord,
the waxing moon rose...
at the time you said it would.
My lord.
I hope you come by...
and watch the lunar eclipse with me.
Why are you down there?
Get up!
No child should be forced to carry this.
It's heavy even for me.
There you go.
- Thank you. - Don't bother.
I only helped...
out of fear of...
missing the tide.
I see.
Sir.
What is a tide?
Oh, that?
The sea beyond that mountain...
is unlike this river.
Ships and boats come and go,
but sometimes there's water,
and sometimes there isn't.
And you can even see the sea floor.
You mean the seawater can disappear suddenly?
Why does it happen?
Who knows?
A sailor once said that it happens...
when the moon pulls the seawater.
It's total nonsense.
The moon has no hands.
The moon pulls the seawater?
Yeong Sil.
Thanks.
What?
For what?
For letting me...
see the sky.
You're talking like an adult...
all of a sudden.
Are you crying?
Why?
Was it tough working at the pier today?
Yes.
It was.
But...
That's not why I'm crying.
The work is really hard,
but being able to see the sky...
is a great thing.
That's what I was thinking...
until I suddenly started to cry.
You know...
Yeong Sil.
I have a question.
The moon and the stars move around us...
just like the sun.
What is keeping them in their places in the sky...
so that they can't run away?
Are they circling us because...
they can't get away?
That's it.
They all follow their own paths.
Something keeps them together...
so that they can move in a certain direction.
I'm off to sleep.
My goodness.
The moon just swallowed Jupiter.
The lunar eclipse might not fall on Thanksgiving.
If my prediction is wrong,
would you be able to find out the reason?
My lord.
I've just witnessed...
something I never saw before.
Could this mean...
the lunar eclipse might not happen?
Something terrible happened.
What?
What's going on?
The moon...
just covered Jupiter.
It's a bad omen.
What are you talking...
Does this mean something bad will happen?
Let me see.
Wait a minute.
The moon...
covered Jupiter?
(Choi Bok)
The moon?
(Ji Kyoung Chan)
That's it.
The King...
will rob...
from his people.
You mean...
- His Majesty... - Hush.
Hurry.
Inform Lord Yu.
Announce me.
He just fell asleep.
I shall wait in the court.
Just inform him that the moon covered Jupiter.
Jupiter...
is swallowed by the moon?
Yes, Your Majesty.
I am sorry to inform you that it is a bad omen.
How bad is it?
Jupiter symbolises blessings and virtue, so...
My blessings and virtue...
are all gone?
Yes, Your Majesty.
This phenomenon was observed...
during the Jin dynasty.
Shortly after that,
the whole nation suffered from a famine.
The whole nation will suffer from a famine?
My people will?
Joseon will?
- What else? - The moon and stars...
describe the relationship between the King and his people.
Jupiter's disappearance means...
- the King... - What?
Are you saying I will kill all my people?
Some kings might do that.
I am sure there were some.
But I am different.
A small flaw is enough to make a king be embarrassed of himself.
But if anyone asks what the most important thing is to me...
If anyone asks,
without any hesitation, I can proudly say that it's the people.
If I am asked to offer my gut to prove my sincerity, I will do so.
If I am asked to offer my liver to prove it, I can do that as well!
They come before my parents.
Before I think about my children,
I think of the people and Joseon first.
You may wonder why. You may ask me if such thing is even possible.
It's because I am the King.
I decided to become the King to always think about the people first.
I took the throne to always worry about the people.
That is my duty.
- Yu Taek Sang. - Yes, Your Majesty.
Is it my fault that Jupiter was covered by the moon?
Answer me now.
When any abnormal phenomena were observed,
all former emperors of China took precautions...
and patiently waited for Heaven to show them the way.
As you are aware, I am desperate for Heaven's will.
Someone told me that there would be a lunar eclipse on Thanksgiving.
As the Chief Officer of Astrology, what is your thought on this?
Please do not believe such a useless prediction.
The next lunar eclipse will occur in the month after this Thanksgiving.
This forecast has been made by Jang Sung Hwee.
Jang Sung Hwee is...
He predicted that the previous solar eclipse would occur in Dongrae-hyun,
and I heard that he even guessed its depth accurately.
I am currently debating between the forecast made by someone who...
accurately predicted the most recent solar eclipse...
and the one made by the Office of Astrology.
Your Majesty. It embarrasses me to speak of this,
but please do not forget how you had to walk down from the altar...
without achieving anything the last time.
Your Majesty. The exact same thing could happen again...
You tell me that I must not forget what happened the last time.
How could I ever forget what happened that day?
If you were me, would you be able to forget that day?
Yu Taek Sang, listen to my words.
I am aware of the possibility that his prediction could be wrong,
but I will choose Jang Sung Hwee's forecast and plan the ceremony.
- Your Majesty! - I will make all those who...
blindly believe the Chinese astronomical calendar watch it.
They will get to see my lunar eclipse ceremony, which...
does not rely on Ming's astronomical calendar.
Wow.
My lord. Today, I saw so many shooting stars falling from...
Myosu which is also called Pleiades.
I recorded the phenomenon because I was so fascinated by it.
I want to record all of my observations like you do.
And my lord. If our records continue to match, there will...
surely be a lunar eclipse in a month from now on Thanksgiving.
The eclipse won't be prevented by Jupiter covering the moon.
(One month later)
Oh?
That's strange.
The moon is looking strange.
The movement of the moon is being delayed.
Why? Why is this happening?
What is the reason? Why is the moon moving slowly all of a sudden?
Could that be the reason?
You mean the seawater can disappear suddenly?
- Why does it happen? - Who knows?
A sailor once said that it happens when the moon pulls the seawater.
It's total nonsense.
The moon pulls the seawater when it comes closer. Then...
does Jupiter pull the moon when the planet is near it?
So it makes the movement of the moon slower...
Gosh, I don't know.
Thanksgiving is three days away.
On this Thanksgiving, all nobles will join the governor...
to hold a lunar eclipse ceremony.
The lunar eclipse ceremony at Suchang Palace will...
coincide with the ceremonies held in other regions.
Hence, you must not make noise during the ceremony.
Drinking, flirting with women, singing, dancing and gambling.
Entertainment of all sorts is forbidden for the time being.
- Yes, Sir. - Yes, Sir.
Run an errand for me with Suk Gu.
Sure, Sir.
Lord Jang Sung Hwee is your father, isn't he? subtitles ripped and synced by riri13
Yes, my lord.
I heard that the King is preparing the ceremony based on his forecast.
The Office of Astrology is not the one who made the forecast?
The Office of Astrology is deeply resenting your father.
I'm not sure why the King is listening to Goryeo's loyalist.
Your father... Well, anyway...
I heard that his method is different from the Office of Astrology's.
Your father's forecast has been chosen, Yeong Sil.
Your father is truly impressive.
Suk Gu. Run the errand by yourself.
- Why? - The lord's forecast isn't correct.
But the ceremony is being prepared according to his forecast.
I need to stop it. I must go to Kaesong and inform His Majesty.
Yeong Sil.
How will you inform the King? How will you meet him?
What are you doing? Hurry up!
This region is in the outskirts of Kaesong, but we should do...
our best to prepare the ceremony so that we don't disgrace the King.
Of course, Master.
Oh? Yeong Sil.
There will be no lunar eclipse three days from today.
Why this little...
What are you doing? Get him out of here!
Wait. Hold on, please. Please inform the King!
There will be no lunar eclipse! The movement is getting delayed.
The moon is moving slower now! Gosh, please.
Lord Jang also said that his forecast could be wrong.
Please pass the message to the King.
I don't want the King to blame the lord later.
Please! Gosh, please...
Please!
You will call musicians for the ceremony?
It will be quite expensive.
Sung Hwee is the one who forecasted the lunar eclipse.
I am more than happy to pay for the musicians for the ceremony.
If that is your wish, I will find talented musicians and...
- have them ready in advance. - There will be no lunar eclipse.
Hee Je. What are you talking about?
Eun Bok has been observing the moon as per Uncle's instructions.
Father, what would you like to do?
If what Eun Bok is saying is true, you should inform His Majesty.
How could we believe what that kid is saying?
Goodness. What should we do about this?
I think you should lock him up for now.
If there is no lunar eclipse,
and he tells people he informed you,
that could cause a problem.
Bring him out!
Yeong Sil.
- What's this about? - What did I do?
- Sir. - Let go.
Let me go.
- Sir. - What's going on?
- Sir! - Let me go!
Yeong Sil!
I can't believe this.
The King rejected our forecast...
and chose Jang Sung Hwee's.
Your Majesty, at tonight's ceremony,
the moon will hear your prayers.
I'm sure of it.
Suchang Palace, Kaesong
Moon.
Move faster.
Please.
Move faster and...
let there be an eclipse.
Make my father's forecast be right.
Make it happen.
(Lee Chun, Hwang Hui)
(Jeon Bae Chun, Yu Taek Sang)
Moon.
Sun.
Let there be an eclipse.
I don't want my father to be sad.
Please help us.
(Dongrae National Civil Service, Busan)
Doesn't this mean...
the servant boy was right?
- How did he know? - I'm impressed.
I apologise.
Blame me.
Do not forgive me...
until I die and my bones...
turn to dust.
I beg of you.
Joseon is a mere infant and...
its people are young.
My descendants will come to the throne after me.
Please do not hate them.
Take pity on them.
I was a fool.
Do not make them pay for...
my shortcomings.
I am begging...
with my whole heart.
Do not turn from Joseon.
Do not abandon Joseon.
- Do not abandon Joseon. - Do not abandon Joseon.
Do not...
Do not abandon Joseon.
Do not abandon us.
- Do not abandon Joseon. - Do not abandon Joseon.
You fool.
Do you still not understand that you ruined the King's ceremony?
You angered the gods with your foolishness,
and they turned against the King.
That is why the ceremony was a failure.
Beat him hard.
Master.
Why did you say there wouldn't be an eclipse?
The moon was delayed.
You meant it was slow and didn't come into the shadow.
What made you think that?
Tell me the reason right now.
The moon...
is pulling the seawater away from us...
so it could be delayed.
Also perhaps...
Jupiter and Venus both pull the moon away...
causing a delay in the moon's movements.
What?
That makes no sense.
If you are right, Jupiter and the moon...
would pull each other so close that they could crash.
Did you cause that fuss...
over something that makes no sense?
Yes, Master.
Everything I told you...
could have nothing to do with...
why the lunar eclipse did not happen.
You have finally come to your senses.
Yes...
Master.
I have come to my senses.
Now that I think about it,
the books I were given never mentioned that...
the seven planets...
went out of line.
What did you just say?
Did you read?
Yes.
Just a short while ago,
you didn't even know the letter for "snake".
The lord read to me...
from a book on the stars.
I memorised what the letters looked like.
Do you even lie now?
It's not a lie.
You can guess the meaning...
from the shape of letter.
You fool!
How dare you say you can read when all you do...
is telling about the shapes!
How dare you!
Do you know what you have done?
Is It wrong for me...
- to learn to read? - Of course it is.
It's wrong for you to read,
and on top of that you have gone against our code of conduct.
What do you mean?
Despite your status, you were curious about astrology.
Despite your status, you showed that you were curious about astrology.
Despite your status, you made an astronomical observation.
Despite your status, you tried to interfere with the King's ceremony.
A slave should know nothing.
You just have to do as you are told.
That is what keeps Joseon afloat.
Shake your head all you want. Nothing will change.
But then...
you are not the type who listens to anyone.
"As selfish as it may seem, I must leave home again."
"For the past 10 years I fled..."
"from Joseon that had been established by the Lee family."
"Now for the rest of my life,"
"I must flee from that child."
"The boy has such talents,"
"but he can do nothing as a slave."
"I do not think I can bear to see it."
"When he realises that..."
"a slave born in Joseon can accomplish nothing great,"
"he will be devastated."
"As his father, I cannot bear the thought."
Stop looking at those stupid stars. It might really get you killed.
"Neither he nor his mother will visit out of hatred for me,"
"but if they happen to befall a fate that could lead to death,"
"please, please do not abandon them or turn them away."
"I beg that you intervene on my behalf."
"From your dear brother."
Yeong Sil. Yeong Sil.
(Dongrae, 1418)
Yeong Sil.
(Jang Yeong Sil)
What?
The blacksmith wants to see you.
Did you ask for me?
The master asked about his hoe.
How come you still haven't fixed it?
I'll fix it later.
I'm not done chopping the firewood.
You fool.
I said the master asked for it!
Fix the hoe right now and chop the firewood at night!
Yes, sir. I'll do that, sir.
Don't you dare slack off. I will beat you up if you do.
- Yes, sir. - You, punk.
I feel for you. Why is he always so mean to you?
I knew he never liked me, but it gets worse each day.
It's not like these are the only hoes people have.
Yeong Sil.
He treats you badly because you are too nice all the time.
Make a stand and talk back once in a while.
Move!
Who told you to touch him?
I was wondering why I hadn't seen him all morning.
I guess he'd gone on the run.
I would have lost him if it hadn't been for Official Jang.
The fool headed for a place he couldn't have thought of.
Someone told him where to go.
Official Jang thinks the man was running along a constellation.
I wonder who told him to do that.
Would fools like us know about things like that?
Yeong Sil.
Did you know he would run?
No, sir.
When will you escape?
What fool would tell you...
if he had such plans?
You have a point.
If you break free while I'm in Hanyang,
my friend who is very good at tracking people down...
will tearing your limps apart alive.
You won't get the pleasure of...
seeing me like that, sir.
How dare you.
You are in no position to joke with a noble.
Beg.
Beg for forgiveness or I'll have you killed.
If he doesn't on the count of three,
kill him.
Please forgive me. The heat from the blacksmith's fire...
seems to have made me lose my mind for a second.
If you really do have plans to run away,
wait until my next visit.
Do that for me, so I get the pleasure of seeing you...
torn apart alive.
- Do you understand? - Yes, sir.
Thank you. Thank you for sparing my life.
- Let's go. - Thank you.
(Hanyang)
(The northern wind blows and a halo shadows the sun.)
(The gods have forsaken Joseon and Goryeo will return to power.)
What would Lord Jang Sung Hwee make of this?
(Lee Chun)
Please find him for me.
For the sake of Joseon.
(Jang Sung Hwee)
Here.
- Take this. - What's this?
What's this?
Toss it over there.
Wow.
The magistrate of Tsushima will be pleased.
It's high-quality nitre.
The nitre and gunpowder.
I'll take them all.
Okay?
Let's see.
Is this real silver?
Of course it is.
I'll put the fire out.
Go inside. There's a lot to see.
Okay.
The silver you gave Suk Gu.
Will you really not tell him?
He'll be upset when he finds out you're gone out to sea.
Give him a few words.
What's that?
A board of constellations?
Why are you rotating the board?
You're a true sailor.
The constellations move around the North Star,
so I have to turn my board accordingly.
Just like the real stars move.
At the exact time?
Yes.
Yeong Sil.
Have you heard of Honsang?
You haven't.
Keep up.
It's all the constellations...
drawn on a ball.
- Like a celestial sphere? - Yes.
Like a celestial sphere.
On a ball.
That's called Honsang.
The owner of the largest ship on Tsushima...
just loves it.
Because rich Ming nobles...
all want one.
If you can make one,
they'll take us straight to...
But...
if I really make one of those,
will he let me...
travel to Ming with him?
Not just that.
I bet he'll give you silver to make many more.
Yeong Sil.
With your gunpowder-making skills, you could do well in Japan.
You could get out of your status...
and even become rich.
Why do you want to go to Ming?
Because there is this instrument...
that you can see the stars with.
If you look at the sky with that,
you can find out exactly how the stars move.
A slave caught on the run loses his limbs.
Are you going to risk that...
for some Ming star-gazing thing?
Wow...
You really have lost your mind.
You're star-crazy.
I like that.
Yes.
I'm crazy about the stars.
I, Jang Yeong Sil is...
a slave in Joseon...
who is crazy about the stars!
Go Gil Su.
You know...
If I could...
figure out the way how the stars move,
I could die happy on the spot.
But...
as long as I live, as a slave in Joseon,
I can't do that.
That's why...
I will risk my life to leave this country.
I must.
(Jang Yeong Sil)
Why didn't I know that...
a dead father is better than...
the one who never visits?
Why are you here?
Make Honsang that revolves on its own.
Then I'll let you board my ship.
- How can you... - I'll do it.
Should we wonder if the sun is the problem?
- Your Majesty. - That is blasphemous!
The sun symbolises the King.
Eun Wol, Yeong Sil's mother.
Do you know how she died?
Jang Yeong Sil was born in Dongrae-hyun in Busan.
His father Jang Sung Hwee was a public official,
