It is easy for young people to learn, but difficult for old people. Every inch of time is an inch of light.

An inch of time and an inch of gold can't buy time.

If a person doesn't work hard when he is young, he will regret when he is old ―― laziness when he is young will make him regret when he is old; Reckless youth makes regretful old age; Idle youth, poor old age

A gentleman's self-cultivation means that his heart is right inside and his appearance is right outside. -(Song) Ouyang Xiu's famous aphorism

Absolute beauty, gone forever, it's hard to wake up in the morning. It is timely to encourage yourself, and time waits for no one. -(Jin) Tao Yuanming's famous epigram

Moral character should be noble; Life should be honest; Mind your manners. You should be polite. -(France) Montesquieu's famous epigram

Quiet to cultivate one's morality, frugality to cultivate one's morality, not seclusion to clear one's mind, not tranquility to be far away. -Zhuge Liang's famous epigram
