List five traditional folk festivals in Song Dynasty.

Many traditional folk festivals in Song Dynasty have been preserved to this day, and there are many similarities in customs and habits, such as New Year's Day (today's Spring Festival), Lantern Festival, Tomb-Sweeping Day, Dragon Boat Festival and Mid-Autumn Festival. Of course, there are still some festival names today, but they have lost the festive atmosphere of the past, such as the solstice in winter; There are also some festivals whose names can't even be found today, such as Cold Food Festival.

The origin here refers to the festival that has been officially celebrated on a large scale by the people, not to the time source of allusions. For example, the story of the Dragon Boat Festival originated from the Warring States Period, but the word "Dragon Boat Festival" was first seen in the local custom of the Jin people in the Zhou Dynasty: "Dragon Boat Festival in midsummer, cooking millet". At that time, people only rowed dragon boats and ate zongzi, which was not standardized. The custom of Dragon Boat Festival has been handed down formally, mainly from the Song Dynasty.
