Hello everyone

I'm the substitute teacher

for the Math Olympiad summer sessions

My name is Zhang Dongsheng

Hello Mr

Everyone welcome to

today's trial class

More people enjoying mathematics

is the best thing that I want to see

Human civilization

in one or two hundred years

made such a huge leap

The greatest hero

is the progress of mathematics

Math is the foundation of all science

Does anyone know

who invented

the earliest rectangular coordinate system?

Descartes

He's a famous mathematician in France

Descartes

So a rectangular coordinate system

is also called a Cartesian coordinate system

There are many different stories

of how he invented the coordinate system

Some say

he dreamed it

Some say

he did it to pursue

a young and beautiful princess

Under the blue sky and the galaxy

there's a little white boat

On the boat is

It's a test to know your level

The purpose of our course

You know each other

Don't deny it

Just you wait

That's his father too

Forget it Pupu

You're leaving after bullying me?

I'll ask the teacher to catch you

Teacher help

I didn't hit you

Zhu Jingjing Let go

Do you think

no one can see us here?

Don't be ridiculous Get down

No way I dare you to say it again

Sure He hates you so much

He hates your guts

Get down first

No I don't listen to you

She fell off?

Chaoyang

Chaoyang

You should calm down

Let's get out of here first

Don't look at it

Get inside

Stop looking

Chaoyang

I'll go that way

See you at the gate

Hello is this the police

Someone fell off the building in the Children's Palace

Yes she fell off

The victim is a little girl

My last name is Chen

I'm a police officer in Guangqiaoli

Chen Guansheng

Okay

I'll secure the scene

All right Hurry up

Stop looking

Hurry up and leave

Stop looking

Come on Don't look at it

Pupu

What were you doing

I'm sorry Yan Liang

Why What's the matter

Let's get out of here

Captain Ye

Hello

Chen Guansheng from the Guangqiaoli station

Ye Jun criminal division

Well

what happened here

I was standing over there

I heard a thump

The child fell off

I called the police right then

and protected the scene

I haven't checked upstairs

Alright Thank you

Let's go upstairs

Captain Ye

How did it go

I asked around

This used to be a geographical garden

Now it's used as a storeroom

Students usually don't come here

Her class was on the fourth floor

Why was she here

The teacher told me

she went to the bathroom

but didn't come back

I took her to the storeroom

on the fifth floor

I wanted to ask her

to stop bullying people

And then

she saw Chaoyang

She

She was shouting at us

as she climbed near the window

Then

I didn't know how it happened

but she fell off

Since she fell off on her own

you two have nothing to do with it

But will they believe us

If you stay quiet now

it'll be hard to explain yourselves

Even if the police buy it

will my dad believe me

Chaoyang

Even if my dad believes me

Zhu Jingjing fell off because of me

Can he forgive me

And Pupu

Do you want her back at the welfare house

Sorry Chaoyang

It's all my fault

I'm leaving

You can call the police if you want

Stop thinking about it

Eat first

Yan Liang

I can't eat anything

Let me see your cut

It's inflamed

I'll ask Chaoyang for some antiseptic

I was too hard on you today

I'm sorry

I'm not angry with you Yan Liang

It was my fault anyway

And I got Chaoyang involved

If his dad knows about it

what will he think of him

Will he lose his father like us

I know what to do

Let's eat first

You want to share my dad?

Dream on

He told me

he only likes me

not you

He hates you so much

He hates your guts

Chaoyang

Mom

Why are you back

Get dressed

We have to go out

Where are we going

To see your father

Jingjing

Jingjing

Jingjing

Jingjing

Jingjing

Jingjing

Don't

Don't take her away

Don't

Why are you here Ms Zhou

He is Chaoyang's father

Chaoyang

Go see your father

Dad

Why isn't he back

Did something happen

He's back

I'm going to bed

Chaoyang

Promise me you'll be safe

Hello

Captain Ye

The report came out

Go ahead

There's blood on the girl's teeth

and a small piece of skin tissue

It's not hers

It means at that time

she had a fight with someone else

It probably isn't an accident

It was sent to the forensic lab

They're trying to find a DNA match

All right I see

Keep investigating

Check the family and social relations

of her family

Go check

her route to school that day

Ask Li

to double check the security

in the Children's Palace

Okay I see

Captain Ye

why is your voice so quiet

My daughter is sleeping

Is there anything else

I'll hang up

Dongsheng

could you sort out the application info

of the Math Olympiad course?

Okay

I didn't expect

something like this

to happen on the first day of summer

What happened

A student in Yu's vocal class

fell off from the fifth floor

Isn't the vocal class on the fourth floor

Somehow the kid went to the fifth floor

She fell out from the storeroom

I have a meeting

When you're done

just put it on my desk

Alright

I got them all back

The CCTV footage

Did you get it

Got it here

This Children's Palace was just rebuilt

There is no monitor on each floor

Only one in the hall

Did the doorman

keep a list of people in and out?

There was a list

but the day it happened

summer courses just started

Parents brought their kids for trial classes

There were a lot of people

from all walks of life

so he didn't have a list on that day

Now we've got our hands full

I discussed with Pupu

We are going to leave Ningzhou

She wants to visit Xin first

We caused you so much trouble

Don't mention it

What about Xin's treatment

We'll try to get the money there

As the saying goes

All roads

All roads lead to Rome

You want to ask a kid

What has he got to do with it

You're right

It's my mother

I'm so sorry

Go to the balcony

Chaoyang

Mom

Mr Ye is here

-Hello Mr Ye -Hello

Don't worry

He's going to ask you a few questions

Are you having lunch

We can talk later

It's okay I'm done

Please take a seat

All right

Come here

Sit with me

Let me take this

Thank you

Do you remember me

I'm Ye Chimin's father

I do Mr Ye

Be relax

I just want to

ask you a few things

When was the last time you saw Zhu Jingjing

I didn't see her much

The last time

was when my dad took me to buy sneakers

It was in last week

Do you know what happened

in the Children's Palace?

I know

My mom took me to the hospital

I mean the day it happened

Didn't you go there

I went to the Math Olympiad trial class

but I left after class

He likes mathematics

My next question

may make you feel uncomfortable

Didn't you see Zhu Jingjing's fall

When I left the class

I saw a lot of people in the yard

I didn't know what happened

I just went home

My mom knows that I don't like to watch

I found out later

Zhu Jingjing was the one who fell off

It's getting windy

Chaoyang

Chaoyang

If you recall anything else

about the Children's Palace

please give me a call

Mr Ye

Have you finished

I have to go back to the resort for work

It's far and I'm afraid to miss the boat

I'm almost done

Sorry for bothering you

Sorry about this

Chaoyang

It's our routine work

We might need to

collect your DNA

If necessary

I will contact your mother

Goodbye Mr Ye

Bye-bye

You should eat less junk food

I prepared everything in the fridge

but you didn't touch it

Don't drink too much soda

It's bad for your health

Okay Mom

Bye

Fold the clothes

Goodbye mom

Don't stay up late and go to bed early

You're old enough

to be responsible for your health

Come down

Are the police suspecting you

I don't know

Let's go back to the boat and pack up

We'll leave early tomorrow morning

Call me when you're in Ha City

Go back

By the way

Take the money

Don't starve Pupu on the way

Thank you

Chaoyang

After my brother is cured

I will bring him to visit you

Don't forget us

I won't

We are friends

Zhu Chaoyang

We meet again
