You have to chop the dumpling stuffing yourself, and the stuffing is a meatball. Jiaozi is oblate in shape, similar to an ingot, symbolizing wealth. Having a family reunion to eat "jiaozi" means that you can increase your wealth in the new year.
Eating jiaozi during the fifth lunar month bears the implication that people expect good luck and happiness. No matter what kind of attention, eating jiaozi during the "Five-Year Plan" entrusts people with the expectation of the Spring Festival, that is, in the new year, they will be able to live a good life without pains and diligence.
