Listening to Professor Ceng Shiqiang's lecture on the Book of Changes, he often said: One yin and one yang call out, how do you understand it?

Yes, the landlord understood it correctly. However, you must be wrong to understand this. Borrow when you should, and don't borrow when you shouldn't. Obey when you should obey a woman, and disobey when you shouldn't. Be a good person when you should be, but not when you shouldn't be. Otherwise, you will get what you deserve; Not being a good person or a bad person, but when to be a good person or a bad person. Can the landlord understand?
