Learn to stay healthy and strengthen your strength.
Learn to learn, learn to desire.
Learn to be a man.
Learn to cooperate, learn to cooperate
Regarding fitness, my idea is that fitness is to make people strong, and it is also spiritual. It is more appropriate to use the word strong.
As for seeking knowledge, it should be tireless, so the word "eager and urgent need" is used instead. Although it is an adjective here, it has nothing to do with the slogan.
Being a simple and clear person, Shakespeare also used "be" to mean "being a person"
Others have no objection.
