In terms of people's aesthetics, there are many papers about Lin Daiyu's appreciation of morbid beauty, and the research is also very thorough. The landlord can search. This is an example.

There is too much morbid appreciation in real life. I think there are several reasons:

1, the public opinion orientation of mass media. Sister Furong, Sister Feng and other online celebrities are all hyped up by lonely netizens, mass media and some business teams with ulterior motives.

2, cultural traditions, religious factors. For example, women's feet in ancient China and female circumcision in some African countries.

3. Personal mental illness.

The above are the main points, personal opinions and lack of authority.
