In the Tang Dynasty, being fat was beauty. To be precise, it is called fullness, called fullness. In the Tang dynasty, people thought that fat women were beautiful, but this did not conform to the aesthetics of that dynasty and was very different from us modern people.
I think the fat meat in the Tang Dynasty should be slightly fat, that is, it looks "fleshy" and relatively plump. Yang Guifei is like this. Most chubby people get tired easily and don't like sports very much, what's more, ancient aristocrats usually go out and rouge and gouache are essential, so Yang Guifei will sweat profusely after a few steps.
