I can't say for sure. From the ancient "long white beauty" to the present "white rich beauty", we can see that there are not many aesthetic observations, just to see whether you are tall, white or not, and whether you look good or not. Of course, Zi holds his heart, which shows that Shi's illness should be very light. Although Fengman was a beauty in the Tang Dynasty, Yang Guifei was not necessarily fat. After all, Yang Guifei was attracted by Tang Xuanzong because she could dance in clothes and feathers. Generally speaking, people who can dance and whose dance can attract the attention of professionals (Tang Xuanzong) will not be fat.
