The

paper

we

know

today

did

not

appear

until

two

thousand

years

ago.

It

was

created

in

China.

No

one

knows

who

first

invented

it.

But

history

does

tell

us

about

one

man

who

improved

the

process

and

this

man

was

Cai

Lun,

who

was

born

during

the

Eastern

Han

Dynasty.

Cai

Lun

often

paid

visits

to

the

countryside

workshops.

Inspired

by

women

who

raised

silkworms（蚕）,

he

used

many

materials

to

make

paper,

such

as

bark（树皮）,

pieces

of

net

normally

used

to

catch

fish,

and

pieces

of

used

cloth.

He

broke

these

materials

down

into

very

small

pieces

and

finally

produced

a

kind

of

paper.

In

105,

Cai

Lun

showed

his

paper-making

process

and

pieces

of

paper

to

Emperor

He

of

Han

（汉和帝）.

His

way

to

make

paper

was

strongly

praised

by

the

Emperor

and

it

soon

got

popular.

The

paper

made

in

this

way,

known

as

Cai

Hou

Paper,

was

used

across

the

country.

Today,

Cai

Lun

is

still

remembered

as

the

inventor

of

the

paper-making

process,

one

of

the

Four

Great

Inventions

of

China.

He

is

regarded

as

the

father

of

the

modern

paper

industry.(
