Therefore, ancient people thought that Yang Guifei was a peerless beauty, which must be in accordance with the aesthetic standards at that time. After all, she is a woman who can be loved by 3,000 people, and Yang Yuhuan was taken away from her son by Emperor Xuanzong of the Tang Dynasty. This shows that Yang Guifei really conforms to the aesthetics of the people in the Tang Dynasty.
Because we like girls to be thin now, but the Tang Dynasty thought that fullness is beauty, just like kim kardashian in the United States. I think many people in China can't stand her figure and think she is fat, but Americans like it very much. So similarly, we may not appreciate Yang Guifei's appearance now, which has something to do with her figure, face and makeup.
After the Tang Dynasty, people would say that Yang Guifei was beautiful, which was inferred from what people said before. After all, they haven't seen Yang Guifei. However, direct historical records and many poets such as Li Bai and Bai Juyi have said that Yang Guifei is beautiful and that Yang Guifei is a disaster to the country and the people. After all, the ancients had a word called beauty disaster. Therefore, people who came to the Qing Dynasty after the Tang Dynasty felt that Yang Guifei was beautiful because of the above reasons.
To tell the truth, we modern people have never seen the true appearance of Yang Guifei. If her appearance still conforms to our aesthetics, maybe we will find her beautiful.
This kind of thing, appearance, is "beauty" that does not conform to our own inner definition. Since the ancients said that Yang Guifei was beautiful, it must be her.
