Urgent, please give me a word, thank you very much.

Perseverance, rotten wood can't be carved;

Perseverance, the stone can be carved.

Are you wasting your time

The leaves are green and yellow, and the world is vicissitudes.

I can, infinitely possible.

Do your best in everything,

A hundred years of tempering, now.

There is no constant victory, only constant provinces.

Study hard, think hard, ask hard and practice hard.

Heaven rewards diligence, and heaven rewards diligence.

Struggle for three years
