In Oracle Bone Inscriptions, "beauty" refers to people dancing with sheep's heads, which is related to primitive witchcraft rituals and sacrifices. That is to say, when people have not defined the meaning of "beauty" artificially (that is, what is "beauty" in writing), in people's primitive thinking, all the scenes of self-respect and self-love are beautiful!

The definition of modern artificial beauty is: the response of people when their own needs are met, that is, the response to aesthetic feeling.

Then we can reasonably classify beauty from this definition of beauty!

Because people's needs change with time and place, the concept of beauty is dynamic and the extension of beauty is uncertain.

According to the way people perceive the objective world (smell, touch, taste, hearing, vision and thinking), beauty can be divided into practical beauty, formal beauty, musical beauty, spiritual beauty and creative beauty.

According to the level of human needs, beauty can be divided into physical beauty, transcendental beauty and spiritual beauty.

According to where people live, beauty can be divided into natural beauty and social beauty.

Beauty can be divided into direct beauty and indirect beauty according to whether there is physical stimulus or not.

Beauty can be divided into practical beauty and signal beauty according to whether the stimulus that causes beauty is the first signal system or the second signal system. ...

But what I want to say is that when people try their best to define beauty, they often ignore this point: beauty has lost a lot around them. Beauty is for narcissism, not for wasting time! Of course, I am not criticizing what people do, because when beauty rises to the field of philosophy, its definition can enhance or beautify people's thinking!

Self-opinion, please forgive me if there is anything wrong! The definition is taken from Baidu Encyclopedia! Thank you, parting makes the heart closer.
