Yan Zhenqing
Night light, five chickens,
It's time for men to read.
Black hair didn't know to study hard,
Bai Shoufang regrets studying late.
The Minnan proverb "Cocks crow at midnight" refers to hardworking people and diligent students who are still working and studying at midnight. At midnight, the light was still on. Shortly after turning off the lights and lying down, chickens crow in the middle of the night, and these hardworking people have to get up and be busy again.
There is an objective phenomenon in the first sentence, which leads to the second sentence: study hard and get up early.
The third and fourth sentences say that if you don't study hard when you are young, it's too late to study now when you are old.
