1. Man shall be made to be a child of his own
This is what Master Guan most often says in the play, and there is a reason for acting and being a person in this sentence. In this lifetime, no matter what people do, they have to work their own. Whether you can succeed in doing something depends on your personal will, on your personal determination, on how much suffering you can endure, and on how much you are willing to pay. No matter how much others help you, it is all secondary, and the key role is still in yourself. If you don't care and give up easily, no matter how others help you, it will be in vain.

2. If you want to be noble before people, you will suffer sin after others
In the play, Master Guan believes that if you want to teach a good apprentice, you must fight, and only by beating can you discipline your own apprentice well, so that they can have a chance to get ahead one day. The apprentice being beaten and scolded by the master is a kind of suffering, and only by accepting the apprentice who has suffered this kind of suffering will he have the opportunity to emerge in the future. In more understandable terms, it is "to eat bitterly, to be a good person".
3. Since the ancients were born in the world, they need to have a skill; since our generation has done business, he should concentrate on hard work; and he will be famous all over the world in the future, according to his youth
This sentence comes from the mouth of the children in the drama class, which is very easy to understand and full of philosophy of life. If people want to live in society in this life, they must have a skill, and if they choose their own profession, they must work hard carefully, attentively and attentively. Whether you can become famous in the future, whether you can do something, depends on whether you have made these efforts when you are young.
4. A man has a man's life
In the play, when cheng dieyi was young, he saw the abandoned child, and the master advised him not to adopt the child, but Cheng Dieyi did not accept the master's persuasion and picked up and adopted the child. However, when this child grew up, he not only did not repay him, but instead took revenge, exposing Cheng Dieyi for framing Duan Xiaolou and trapping them in an unfavorable situation, which also directly led to the suicide of Shimu Juxian. It is another story of "the farmer and the snake", I know why today, a person has a life, perhaps, Cheng Dieyi should have listened to the master's advice.
5. No matter how capable a man is, he will not be able to defeat the Mandate of Heaven in the end
The meaning of this passage in the play is that even if people have more abilities in this life, they will not be able to escape Providence in the end. I think this sentence is the best true portrayal of the film's plot. All the people in the play, from the high-ranking officials and nobles to the people of Li Min, cannot escape Providence.
