former

Return to one's former self

(Ice Source)

The falling leaves in summer already know that autumn is coming.

White hair on his head indicates that he feels lonely.

If I had known that everything was empty, why would I still go for it?

Autumn tides will swell up again in spring.

译:

复由身

(冰源)

盛夏落叶已知秋，

人生华发已知孤。

早知空空何为求，

秋水潮去春复鼓。
