On February 2nd, people should add a dragon to everything they eat. For example, noodles are dragon whiskers, jiaozi is dragon ears, and pancakes are gentian. In addition to these "eating dragons", the food they eat every day should also be applauded, such as tofu called Doufu, mustard tuber called borrowing money and so on. In jiaozi, some are shaped like ingots, others like ears. The dragon looks up and eats jiaozi, which is called "eating dragon ears". On the day when the dragon looks up, it pays attention to eating "vegetarian jiaozi", that is, there are both meat and vegetables in the stuffing, and the homonym of "vegetarian" is "wealth", which conveys the message that the New Year's financial resources are rolling in. Eating jiaozi on February 2nd is a traditional custom, which means good luck. Solemnly declare: the answer is for reference only, please don't be blindly superstitious.
