Please study hard next time. Is it a famous epigram or an epigram? Thank you very much.

Hello, I'm glad to answer your question. The answer is as follows:

This sentence should be regarded as a famous saying, which was said by Chairman Mao.

Said by:1951At the end of September, Mao Zedong received an Anhui delegation attending the National Day, including Ma Sanjie, a little hero crossing the river. Mao Zedong asked her about her study with concern, gave her a beautiful notebook and wrote an inscription on the title page: Study hard and make progress every day. These eight-character inscriptions quickly spread throughout the country.

I hope my answer is helpful to you. If you are satisfied, please accept it.
