Of course it's true.
In fact, not only Zhao Feiyan, there are many other people who were recorded as "able to dance on the palm of their hands" in history. For example, Zhang Jinyuan, the dancer of Yang Kan, had a waist of 1 foot 6 inches, which was very slim and could dance on the palm of her hand. There is also the Qinhuai dancer Xu Cuilin, "skin jade snow, eyes like a picture", and "body as weak as the clothes, can dance on the palm". These are all famous, if you doubt one, then all these records to doubt. It could be underestimating the talent of others, or simply not being able to visualize what you haven't seen, or not being good at reasoning based on what you can see.
So let's push for the subject.
Zhao Feiyan this person, and the latter two are in fact the same, the main characteristic is "thin", if not thin, then it is difficult to palm dance, will be the supporter of the crushed to death. There's a Chinese idiom called "fat and thin", which refers to the fact that Yang Yuhuan, Li Longji's consort, was rather fat:
And Zhao Feiyan, the court dancer favored by Emperor Chengdi of the Han Dynasty, was thin, but not withered:
Well, the picture of Yang Yuhuan is a joke, but in fact, Yang Yuhuan's body was very beautiful, and her weight wasn't too much," said Professor Wang Shuanghuai, a historian. Historian Prof. Wang Shuanghuai had speculated it was 120 or so pounds. Yang Yuhuan was also a very good dancer, but she wouldn't have been able to palm dance unless she was on top of An Lushan.
In fact, it is indeed documented that An Lushan, a big fat man, weighed more than 300 pounds. But people run up no effort, fit as a fiddle, waves. He when that catch life will be, is to the enemy-occupied areas to catch people, caught after escorting our interrogation. He put people down this skill is very good, thanks to his weight. An Lushan even in his old age, will still dance like the wind: "(An Lushan) in his later years more fat, belly hanging over the knee, weighing three hundred and thirty pounds, every walk to the shoulders of the left and right to lift and pull its body, in order to be able to move. To Xuanzong before, for Hu Xuan dance, as fast as the wind."
Yang Yuhuan can not dance on the palm, Zhao Feiyan can.
How much did Zhao Feiyan weigh?
"She is slim and slender, but not too thin to hold", about eighty pounds. This is the same as many acrobats or ballet dancers, and usually the ones who dance on them are female and thin. Here's a comparison of the appropriate weight and height for a ballet dancer, and Zhao Feiyan's figure is more detailed than that.
And we often see this kind of dance performed on others.
Such as the "Knee Dance":
"Shoulder Dance":
"Head Dance":
and the one being discussed right now. "Palm Dance:
Of course, palm dance is not limited to one person, but can be performed by a group of people:
Why do you doubt that ancient Chinese dancers even knew how to do palm dance? Maybe you don't get it, and think that "palm dancing" is when someone stands with their hand outstretched and lets a person dance on it.
It's exhausting, but even so, some people can do it (just ask a barbell lifter), just not for very long. But what if it's supported by elbows at the waist? The amount of weight that can be supported could easily exceed Zhao Feiyan's weight.
So, in summary, according to historical data and notes, and data projections, the actual scene of modern dance, Zhao Feiyan "can palm dance" this thing is not even need to doubt.
