The name of tangyuan is similar to the pronunciation of "reunion". Taking the meaning of reunion symbolizes family reunion, harmony and happiness, and also places good wishes for future life. People also miss their departed relatives and place their best wishes on their future life.
Because the Lantern Festival is a reunion festival, both married and unmarried female friends should have a lot of love during the Lantern Festival. So female friends remind you to eat an odd number of Yuanxiao, such as five, seven, nine and so on. Of course, married or unmarried male friends should eat even numbers during the Lantern Festival, such as 6, 8, 10, so that your love will be open and your peach blossom will be lucky.
Eating glutinous rice balls means reunion and increasing age. Traditional red and white glutinous rice balls can also attract marriage and popularity respectively. The time to eat jiaozi is not necessarily the winter solstice. As long as the family can get together, just make winter a few days in advance. However, the number of jiaozi must be paired to be lucky.
