The names of these two beauties are always talked about by people in history, and Zhao is one of the four beauties in history. There is a saying called "as light as a swallow", which is used to describe Zhao's graceful posture and dancing like a swallow. These two beauties, Hurd Yan Fei, served Han Chengdi for ten years and spoiled the imperial harem without leaving a son and a half. The reason is that the two sisters used some illegal drugs to keep young and beautiful, which led to infertility.

First, Zhao entered the palace. The two sisters, Yan Fei Hyde, have been beautiful since childhood. Although I was born in poverty, I have an unspeakable temperament. Zhao Yanfei was sent to learn dance when he was a little older. So when Emperor Han Chengdi first saw Zhao Yanfei, he was dumbfounded. Even after the dinner, I urged her to return to the palace. And Ye Zhao is very calculating. She knew that it was impossible for a man to win his heart easily, so she deliberately refused the favor of Emperor Han Chengdi three times. Emperor Han Chengdi became more and more obsessed with her.

Second, Zhao is very hard on himself. In order to get the full attention of Emperor Xian, she introduced her sister to Emperor Xian. Zhao Hede became more scheming, saying that she would rather die than enter the palace. So it aroused the strong interest of Emperor Han Chengdi, and finally the Zhao sisters went to the palace for a party every night. But the emperor, as the statue of the Ninth Five-Year Plan, certainly has all kinds of beautiful women around him. In order to stay young and beautiful forever, Yan Fei Hurd used a medicine called Xiji Pill. This medicine can make the body emit a special fragrance and keep the face young.

Thirdly, after the infertile Yan Fei Hurd used the information, the slim figure made Han Chengdi addicted to beauty all day. However, excessive use of Xiji pills also has side effects. Because the ingredients of Xiji Pill are mainly musk, Yan Fei Hede has kept Liu Gongchong away for more than ten years and still has no daughter and a half.
