What are the traditional festivals in China? What are the customs?

Most important traditional festivals in China are related to the calendar. The new book "China Festival-Illustrated Folk Traditional Festivals" (Fujian People's Publishing House, June, 2005) by Ms. Li Lulu, a researcher at the National Museum of China, classifies the statistics of the more important traditional festivals in China into 20, of which 16 come from the seasonal intersection of the sun and the moon, or are related to them: Spring Festival, beginning of spring, Lantern Festival, Zhonghe Festival. Shangyuan Festival (March 3), Tomb-Sweeping Day, Lantern Festival (June 6), summer festivals, Valentine's Day in China, Mid-Autumn Festival, Double Ninth Festival and winter festivals are all closely related to the rhythm of the weather. On the surface, it has nothing to do with the weather, such as Dragon Boat Festival, Laba Festival (the eighth day of December), Kitchen Festival (December 23rd) and New Year's Eve Festival. Folk beliefs believe that May is a poisonous month and the fifth day is a poisonous day. There are five poisons, namely snakes, centipedes, scorpions, lizards and toads. This month is full of disasters, even the baby will die. Therefore, we must take various measures to prevent it. Avoiding the five poisons is the original intention of the Dragon Boat Festival. Laba, offering sacrifices to stoves and New Year's Eve are all "companion festivals" of the Spring Festival, which are naturally related to the times, while the other four festivals are "Man Victory Festival" on the seventh day of the first month, "Bathing Buddha Festival" on the eighth day of April, "Ghost Festival" on July 15th and "Xia Yuan Festival" on October 15th.
