Making dumplings symbolizes joy, auspiciousness, happiness and beauty.
Since dumplings look like ingots, people eat dumplings during the Spring Festival to bring wealth. At the same time, the dumplings have fillings inside, which makes it convenient for people to put various happy and auspicious things into the dumpling fillings, so as to express everyone's good wishes for the new year. People put kumquats and sugar in dumplings, and eating them means the days ahead will be sweeter.
Eating dumplings during the Winter Solstice is to remember the kindness of the "Medical Saint" Zhang Zhongjing's "Quhan Jiao Er Soup". There is still a folk saying in Nanyang that "if you don't bring dumpling bowls during the winter solstice, your ears will freeze off and no one will care".
