This is a night for men to study. Black hair doesn't know how to learn early, but a bald head regrets reading. Who wrote it?

Yan Zhenqing

Persuasive learning

Yan Zhenqing

Night light, five chickens,

It's time for men to study.

Black hair didn't know to study hard,

Bai Shoufang regrets studying late.

The author introduces:

Yan Zhenqing (August 23, 709-784), whose real name was Chen Qing, was born in Jingzhao Wanzhao (now Xi, Shaanxi) and his ancestral home was Langxie Linyi (now Linyi, Shandong). Yan Shigu V was a famous politician and calligrapher in the Tang Dynasty.

In the 22nd year of Kaiyuan (734), he was admitted to imperial academy. He was appointed as the censor for four times and moved the temple to serve the censor. Rejected by Yang, the powerful minister at that time, he was demoted to the plain satrap and was called "Yan Plain". When Tang Suzong arrived in Fengxiang, he was awarded the title of Minister of Constitution, and later he moved to imperial academy. When Tang Daizong was an official, he went to the official department of Shangshu Province, and a prince and a surname named him Duke Lu, which was called Duke Yan Lu in history. In the first year of Xingyuan (784), he was framed by Prime Minister Qilu and sent to Li Xilie, the leader of the rebel army, to report, but he refused the thief in awe and was finally strangled.

Yan Zhenqing founded "Yan Ti" regular script, which is called "four masters of regular script" with Zhao Mengfu, Liu Gongquan and Ou Yangxun. Together with Liu Gongquan, they are called "Yan Liu" and "Yangu".

Translation:

Hard-working people and students are still working and studying in the middle of the night, and the lights are still on in the middle of the night. Turn off the lights, lie down for a short rest, and soon, the chickens crow at five o'clock, and these hard-working people have to get up and be busy again.

If you don't know how to study hard when you are young, it will be too late to study when you are old.
