only

imagine

how

travellers

felt

when

saw

the

oasis

of

Dunhuang

ahead

of

them.2.If

look

up,

you

can

see

the

the

Ming

Dynasty,

trade

and

Dunhuang

was

not

as

as

used

to

be.5.Gradually,

it

faded

from

even

though

it

was

once

such

a

great

city.6.Given

that

the

theme

of

the

Expo

was

to

promote

cultural

exchange

and

strengthen

mutual

cooperation

between

the

countries

along

the

Silk

Road,

Dunhuang

was

the

ideal

place.
