During the fair, all the flower nursery holders around Chengdu will take their rare and precious flowers, potted flowers and potted landscapes to Qingyang Palace, and then set up stalls to exhibit and sell all of them. According to legends, the fair is to commemorate the founder of Taoism, Li Laojun, (also Lao-tzu, a Chinese philosopher in the Spring and Autumn Period) whose birthday is the Feb. 15 of the Lunar calendar. In addition, every February always sees a variety of flowers blooming. So the day is also considered as the birthday of flowers.
