In feudal times, Confucius and Mencius put forward the rules and regulations that bound people's thinking, such as justice and ethics. Of course, we can't say that these rules and regulations must be feudal, but they must be bad. After all, they still regulate people's thinking to a certain extent, although they are also limitations. However, this freedom is a very broad concept, and it is also important to treat it dialectically. The conditions of use are against human relations or in broad daylight.
