Why do you want to eat pig's trotters on February 2?

Because eating pig's head on February 2 represents good luck, and pig's head is an auspicious sign to turn the corner and make progress. The statement about eating pig's head on February 2nd is as follows:

Since ancient times, pigs, cows and sheep have been used to worship the gods, and later it was simplified to the head of the three animals, and the pig head is one of them. Moreover, there is an allusion. According to a story recorded in Qiu Chi Notes in Song Dynasty, Wang Zhongling was very hungry after pacifying Bashu, so he broke into a temple in a small village, but he met a drunken monk. Wang Zhongling was furious and wanted to cut it, but the monk was completely fearless. Wang Zhongling was very strange, so he asked him for food.

Not long after, the monk presented a plate of "steamed pig's head" and wrote a poem for it: "The mouth is short and the body is fat, and the Chinese medicine seedlings are eaten for a long time. When steaming, the banana leaves have been wrapped, and when cooked, water them with apricot paddles. Red, fresh and elegant, called Jin panting, ripe and soft, really like jade. If there is no comparison between hairy roots, felt roots will eat vines. " Wang Zhongling ate steamed pig's head, and was very happy to hear the funny and unique "pig's head poem", so he named the monk "Master of Purple Clothes". It seems that the pig's head is really delicious and an auspicious symbol of turning the corner.

In order to "warm his life", some places have the custom of holding a "land meeting": every household raises funds to celebrate the birthday of the land god, burns incense and sacrifices at the land temple, beats gongs and drums and sets off firecrackers. People in China think that dragons are auspicious things and masters of wind and rain.
