How did moral ethics come into being?

China's traditional ethics has two influences. First, the positive impact. For example, the three cardinal guides and the five permanent members, such as the golden mean. It has played an important role in history and still affects all aspects of our lives, especially Confucianism, which has important guiding significance not only in feudal society but also in today's society. The ancient family concept and unmarried women's concept of chastity play an important role in the stability of today's society. Look at many divorce phenomena in today's society, as well as abortion, which are the consequences of abandoning traditional concepts and doing whatever they want. Second, the negative impact. Especially some ethical rules for women. For example, foot binding, such as leaving a chastity memorial arch after her husband's death. For example, Confucius said that "only women are difficult to raise." They are all discriminatory against women and should be abandoned.
