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 gods. Later, it was simplified to the heads of three animals, and the pig head is one of them. Moreover, there is an allusion. According to a story in Qiu Chi's 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 surprised and asked him for food.

Soon after, the monk presented a plate of "steamed pig's head" and wrote a poem for it: "The mouth is short and fat, and the Chinese medicine seedlings are eaten for a long time. When steaming, the banana leaves have been wrapped. When they are ripe, water them with apricot leaf paddles. Red, fresh and elegant, makes Jin breathless, while ripe and soft are really jade. If there are no hairy roots to compare, the felt roots will eat vines. " Wang Zhongling ate the steamed pig's head and was very happy to hear the interesting and unique "pig's head poem", so he named the monk "Master of Purple Clothes". It seems that pig's head meat is really a delicious food, and it is also an auspicious symbol of turning the corner and making rapid progress.

Extended data:

In southern China, February 2nd is the birthday of the father-in-law of Land, which is called "Land Birthday". In order to "warm the life of the land father-in-law", some places have the custom of holding "land meetings": every household raises funds to celebrate the birthday of the land god, burns incense and sacrifices in the land temple, and sets off firecrackers with gongs and drums. People in China think that dragons are auspicious things and masters of wind and rain.

On the second day of February in the lunar calendar, the dragon will rise to heaven. As far as solar terms are concerned, the early February of the lunar calendar is between "rain", "fright" and "vernal equinox". Many places in China have begun to enter the rainy season, and people will hold dragon ceremonies to pray for rain and release them for a bumper harvest.
