I don't know when it started. In the costume dramas of the Tang Dynasty, women were all plump. I think this has a lot to do with many paintings in the Tang Dynasty. We have a very long history and culture. When we study these cultures, we can see the characteristics of each dynasty. In the famous pictures of ladies in the Tang Dynasty, the female characters we saw were plump and beautiful. But most of these paintings are from the middle Tang Dynasty. Because the society at that time was relatively stable, people's lives were relatively rich, especially the aristocratic class, and their lives were relatively luxurious. Under such conditions, these dignitaries gradually gain weight and become fat. As the mainstream class of society, their bodies also guide the current aesthetics.
However, there is an essential difference between fullness and obesity. Fat is actually a relative concept. For women in the Tang dynasty, fullness is a sign of good living conditions, but it is still graceful, not bucket-shaped. Even as the number one beauty in the Tang Dynasty, did Yang Yuhuan have it? Ring fertilizer? But people jump up with colorful feathers. This is a touching world that will attract a generation of emperors to accompany and love. The image of Yang Yuhuan we see is plump, not fat. In today's words, plump at best? Look thin and feel a little fleshy? That's all.
But in the late Tang Dynasty, because of social unrest, people no longer lived and worked in peace and contentment, and began to wander around. There are fewer plump women, and the aesthetics slowly return to the standard level. In fact, even now, our obesity is only a relative concept. Of course, we still hope that people don't grow too much meat, because that will not only affect their appearance, but also affect their health and easily lead to various diseases.
