Because in ancient China, many dynasties regarded thinness as beauty, but for the Tang Dynasty, ancient people seemed to be fatter. In fact, it is debatable that fat is the beauty of the Tang Dynasty.
Extended data
The view that fat is beautiful has a long history in the Tang Dynasty, but interestingly, basically no one in the Tang Dynasty said that fat is beautiful, which can best prove that they regard fat as beautiful. It seems that people are used to using "fat and thin" to describe Yang Guifei, and the description of "talented and talented" in "Learning from each other".
In fact, the concept of "being fat is beautiful" in the Tang Dynasty is more "strong" than "fat". In addition, the strong interest in Buddhism and the artistic processing formed by unofficial history's over-exaggeration of the plump beauty in the Tang Dynasty made the concept of "taking fat as beauty" in the Tang Dynasty a misunderstanding of beauty. So the favorite sentence "I am a beauty of the Tang Dynasty" is actually a "false proposition".
