Is "study hard and make progress every day" the motto?

"Study hard and make progress every day" was written by Chairman Mao after he learned that Chen Yongkang, an 8-year-old pupil of Jinchang Primary School in Suzhou, was injured by a spy, and he made a banner to give to children in Chen Yongkang. At the same time, he issued a call for "study hard and make progress every day" to teenagers all over the country.

study hard, and make progress every day means listening, watching, reading and writing carefully, practicing and practicing repeatedly, and paying attention to improving your spiritual realm, moral level and business skills every day.

This sentence has long been a monument to the majority of teenagers and primary school students.
