Zhang Daqian's inscribed couplets
People need to be bold in difficulties and calm in ambiguity! Nothing can be generalized! Everything has a good side and a bad side! You can't use generality to represent everything! Believe in yourself in everything, don't believe in anything, and don't believe it! The important thing is that you have your own opinion! From one thing, you can see a person! It can be said that a small matter can reflect a person's heart! You have to consider people from all aspects, and in what ways does this person do well!
