Yang Guifei is a peerless beauty. She is plump and sexy, which fully embodies the graceful beauty respected by the Tang Dynasty. According to legend, Yang Guifei likes to eat two things most in her life. This first kind, litchi, is evidenced by the poem of the Tang Dynasty poet "Riding a princess in the world of mortals and laughing, no one knows it is litchi". In China, litchi is generally produced in Lingnan. According to Bai Juyi's preface to litchi day, this kind of fruit changed color in two days and taste in three days after leaving school. After four or five days, the fragrance disappeared. "Lingnan is thousands of miles away from Chang 'an, the capital where Yang Guifei lives. At that time, there was no invention of aircraft, so it could not be transported by air. In order to let Yang Guifei eat fresh lychees of all colors and tastes, she had to send someone to eat them. According to this allusion, the chef in the palace specially created a dish called "Guifei Litchi".
