Meng Changjun, the Emperor of Shu after the Five Dynasties, had a concubine named "Mrs. Huarui". She is not only charming, but also likes flowers. One year, she went to the flower market. Among the flowers, she saw clusters of hibiscus flowers rolling in like colorful clouds in the sky, and she especially liked them. In order to please his beloved princess, Meng Changjun also made an imperial edict: "In Chengdu, there are all kinds of hibiscus planted on the head of the city, which will bloom in autumn and look magnificent." . The emperor said,' the ministers said that Shu was a golden city since ancient times, and now it is a real golden city.' "When bloom comes next year, Chengdu will be' forty miles like a splendid place'. In October of the 12th year of Zheng Guang, the greening project of Mengchang was completed, and Mrs. Huarui boarded the tower together to watch dozens of hibiscus flowers in Chengdu. Since then, Chengdu has gained the reputation of "City of Furong". Later, after the demise of Shu, Mrs. Hua Rui was swept into the harem by the emperor of the Song Dynasty. Mrs. Hua Rui often misses Meng Chang and secretly treasures his portrait to express her feelings of missing him. When Zhao Kuangyin found out, he forced her to hand over the portrait. However, Mrs. Huarui refused, and Zhao Kuangyin killed her in a rage. Later generations respected Mrs. Hua Rui's loyalty to love and regarded her as the "hibiscus flower god", so the hibiscus flower was also called the "love flower".

Since then, later generations have used hibiscus flowers to express their love for each other in memory of Mrs. Huarui.
