According to Tang Shi, people in the Tang Dynasty regarded obesity as beauty. Some scholars may think that Yang Guifei's eating litchi at that time was related to the decline of national strength at that time, so pen and ink have always satirized Yang Yuhuan. But this is probably not the case in reality. According to the aesthetic standards of Emperor Xuanzong of the Tang Dynasty, Yang Guifei certainly won't be very fat.

Some scholars say that the imperial concubine is wrong about her country and thinks that she is a disaster. Those literati accused Yang Guifei of not being plump, but directly getting fat. They said that this Queen Yang was too fat, and she would sweat profusely in summer, and she was so hot that she was sweating all over. She had to eat fresh litchi to spend the hot summer. These are legends, there is no real historical record, but it is these rumors that have been mocking this woman.

Looking at Tang Xuanzong again, from his artistic taste, Cai Yu is his work, and he has his own understanding of beauty. Li Deyu recorded the concept of Xuanzong in his book, that is, to be "slender and fair", that is, to be tall and slim with fair and smooth skin. Too fat, too sorry for the title of emperor.

It is also said that Yang Guifei is too fat, or those people deliberately satirize Yang Guifei and satirize her for delaying the affairs of the emperor with her obese body. However, if women restrict the emperor according to history, it must be that the emperor is obsessed with state affairs at this time, and those who are sour dare not directly satirize the emperor and can only kill a weak woman.

However, some people say that this way of dealing with the image of adult women is probably intentional, aiming at highlighting the glory of the court/aristocratic life in the Tang Dynasty, but not necessarily completely realistic.
