What are the allusions to eating pig's head on February 2nd in northern China?

There is also a saying that pig's head meat is eaten on February 2. 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. According to a story recorded in Qiu Chi's Notes in the 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 he didn't know that the monk was afraid. Wang Zhongling was very surprised and asked him for food. Soon the monk presented a plate of "steamed pig's head" and wrote a poem for it: "The monk said that when steaming, the banana leaves were wrapped and watered with apricot paddles when cooked. 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 it is also an auspicious symbol of turning the corner and making rapid progress. Now there is a famous dish called "roast pork face", which can be served after twelve steps, such as selecting ingredients, cleaning, spraying, soaking, making sauce and cooking for more than ten hours. There are three kinds of "roast pig face", one is the original taste; The second is to dip in the sauce; The third is to roll pancakes to eat. Every way of eating has a different taste. "Roasted pig's face" is fat but not greasy, the meat and bones are separated, and it tastes delicious, which brings beauty and brain-strengthening effects to modern people. Eating modern "pork noodles" on February 2 nd and recalling the history of ancient catering is really a perfect experience of blending contemporary and history.

The folk proverb says, "On February 2nd, the dragon looked up." Around the second day of the second lunar month is one of the 24 solar terms. It is said that the hibernating dragon was awakened by the rumbling spring thunder on this day and stood up. Therefore, the ancients called the second day of the second lunar month the Spring Festival, also known as the Dragon Head Festival or the Qinglong Festival. Therefore, on this day, people go to the river to worship the dragon god.
