Among the Zhao sisters in the Western Han Dynasty, who was as light as a swallow?

Zhao Feiyan, as light as a swallow, is good at dancing. In the first year of Yong Shi, Zhao Feiyan became the new queen of Emperor Cheng of Han Dynasty. Emperor Cheng specially asked craftsmen to build a magnificent imperial boat in the Taiye Pool of the Palace, called "Hegong Boat". On one occasion, Fei Yan and Cheng Di went boating on the lake, and when it was beautiful, Fei Yan danced for Cheng Di. Unexpectedly, when she was dancing, a sudden gust of wind almost blew Zhao Feiyan away. Fortunately, Feng Wufang of blowing sheng next to her grabbed the queen's feet, and Fei Yan continued to sing and dance. This is the origin of the legendary allusion that "Fei Yan can dance on the palm".
