Ai Qing wrote a poem, the first sentence "This world, everything is ancient.

This world,

Everything is old,

Only love,

But always young;

This world,

Full of deception,

Only love,

But always naive;

As long as there is love,

Fish swim in the water,

Birds are flying in the sky,

Night is also transparent;

Lovelorn,

A piano with broken strings,

A lamp without oil,

It is also very cold in summer.
