Thank you so much for your correction!

I don't know you're level but this is very good!! Here's some corrections for the harder sentences: They are the team members of the class that is about knowing yourself. = They are the team members of the class that teaches getting to know yourself. OR They are the team members of the class that deals with self knowledge and gaining a deeper understanding of yourself/oneself. One of them is a kind men who likes serving others… = One of them is a kind man who likes helping others… serving others in difficulty - this is an uncommon expression but not wrong. Depending on the situation, it might be better to say = helping/serving people in need And the other members is a rational men = and the other member is a rational man who doesn’t see whether people’s action is wrong, he always wants to know what result in these action. = who is not interested in whether people’s actions are wrong, he is more interested in the results of those actions.
