Reunion dinner, also known as New Year's Eve and Reunion Dinner, is the most important dinner for families in China at the end of the year, symbolizing family reunion and happiness. As early as the Han Dynasty, people in China had the custom of having a reunion dinner.

Everyone will eat jiaozi at the reunion dinner: eating jiaozi means "making friends when I was young", while "Zi" means "Zi Shi", which is homophonic with "Jiao" and means "Happy Reunion" and "Good luck". In addition, because jiaozi looks like an ingot, eating jiaozi in the New Year also has the auspicious meaning of "the way to make money", so eating a reunion dinner is a beautiful symbol.
