1 was left in memory of Zhang Zhongjing, a "medical sage", who gave up medicine on the solstice.

Zhang Zhongjing, the "medical sage", resigned and returned to his hometown. It was winter, and he found that many people's ears were frozen. He asked his disciples to set up a medicine shed and cauldron in Dongguan, Nanyang, and then fished out the mutton and medicine and chopped them into ear-shaped "charming ears" with bread.

After cooking, give everyone who comes to ask for medicine two Joules and a big bowl of broth. People ate "Joule" and drank "Quhan Decoction", and they were all hot, their ears were hot, and their frostbitten ears were cured.

When you eat jiaozi on the solstice in winter, you will never forget the kindness of Zhang Zhongjing, a "medical sage", in "Quhan Joule Decoction". Up to now, there is still a folk song in Nanyang, which is called "jiaozi Bowl, and nobody cares about frozen ears." .

2. The main reason for eating jiaozi is that I hope to get rich in the future.

Jiaozi is shaped like an ingot, which means getting rich. This is the most reasonable explanation I think. Therefore, eating jiaozi means getting rich.
