According to legend, the third day of the third lunar month is also the birthday of the Queen Mother, and it is the day when she holds a flat peach party. There is a poem in Zhi Zhu, Beijing, describing the grand occasion of the temple fair in the Flat Peach Palace: "Born in spring on the third day of March, the Flat Peach Palace burns incense; The wind rises slightly along the river and the red dust is everywhere. " Legend has it that the Queen Mother of the West was originally the patron saint of a primitive tribe in western China. She has two magic weapons: one is to take the elixir of life, and the other is to eat peaches-flat peaches, which can prolong life. The legendary Chang 'e flew to the Moon Palace after stealing the elixir from her husband Hou Yi. Since then, in some strange novels, the Queen Mother of the West has been described as the god of longevity.

So "March 3rd" is also called "Millennium Festival of the Queen Mother". The traditional folk customs of this day are spring outing, mountain climbing, temple fairs and love songs. Therefore, "March 3rd", as a unique festival in China traditional culture, has been passed down to this day.
