One inch of time, one inch of gold

In the blink of an eye

Time flies by like a fleeting horse

In the blink of an eye

Karma Be skilled in diligence, be lazy in play, succeed in thinking, and be ruined by following.

Black-haired people don’t know how to be diligent and study early, white-headed people regret studying late.

My life also has a limit, but knowledge also has no limit.

The days are like rosary beads, slipping by one day after another, stringing together into weeks and stringing into months

The years are gone and it is difficult to give up the career

The golden age is in front of us, not behind us

Time is the capital of intellectual workers

The knowledge of literature is the gate of learning

Genius is nothing more than long-term patience, work hard!

Knowledge is like candlelight, it can illuminate one person and countless people
