Why does the dragon look up and eat beans on February 2?

According to folklore, the custom of eating beans on February 2 began in the Tang Dynasty.

This day is the beginning of spring ploughing. The emperor will go to the fields to help plow the fields, and the queen will go to the fields to deliver meals to them, which is an example for the people. Folk fried corn beans have the meaning of divination, and the flowering size of corn beans indicates a bumper harvest in the new year.

Since then, people have formed a habit. On February 2nd every year, people pop popcorn and some fried beans. Adults and children still read: "On February 2, the dragon looked up, the big warehouse was full, and the small warehouse flowed." In some places, kitchen waste ash is scattered in the yard to form a big circle, and whole grains are put in the middle, which is called "hoarding" or "filling the warehouse". It means to wish the grain a bumper harvest and a full warehouse. During festivals, the names of foods in various places are generally labeled as "dragons". Eating jiaozi is called eating "dragon ears". Eating spring cakes is called eating "Longlin". Eating noodles is called eating "dragon beard meat" Eating rice is called eating dragons. Eating wonton is called eating "longan". The answer is for reference only. Please don't be blindly superstitious.
