The main contents of Confucian ethics

In the Confucian doctrine, the ruler, the subject, the father and the son are the center of the ethical system, that is, "the ruler is the order of the subject, the father is the order of the son" "the ruler is the order of the subject, the father is the order of the son" "the ruler is the order of the subject, the father is the order of the son", which means that: the one who is the ruler is the ruler, and the one who is the subject is the subject, the subject is the subject, and the subject absolutely obeys the ruler, and cannot exceed the prescribed number of rites, otherwise it is disloyal. A subject must not exceed the prescribed rites, otherwise it is considered disloyal. The relationship between father and son is similar to that between ruler and subject, otherwise it is unfilial. Unfaithfulness and unfiliality were the greatest sins in feudalism. There were also some other ancillary ethical rules, such as the Three Obediences and Four Virtues for women, no marriage between a man and a woman with the same surname, and marriage between a man and a woman with the same family name, etc., but these were not the most important ones. The ethical concepts of the ruler, the subject, the father and the son maintained the stability of the Chinese feudal society to a large extent.
