Ethics refers to the principles and norms that should be followed when dealing with the relationship between people and between people and society.

Morality is a kind of social ideology, and it is the norm and criterion of people's life and behavior. Ethics can be regarded as synonyms in a certain etymological sense, which refers to social moral phenomena.

But there are differences between them. Morality refers to the sum of people's code of conduct and norms. Ethics generally has the same coherent meaning and is used in interpersonal relationships, so "ethics" goes further than "morality" and is a summary of moral phenomena.
