1) stealing chopsticks. In some areas in the past, when the groom picked up the bride, he had to assign a young man to "secretly" take a pair of chopsticks from the bride's family to get the meaning of having a baby soon!
2) add chopsticks. When the groom goes to pick up the bride, he should bring a pair of red chopsticks. He took the bride back, and the groom's family wanted to add a pair of red chopsticks, indicating that the man's family had added a pair of chopsticks.
3) throw chopsticks. When they get married and have a new house in Jiangnan, they will throw a pair of dragon and phoenix chopsticks out of the window, and a pair of chopsticks will fall to the ground. Bang, everyone will say "chopsticks, chopsticks, a baby is coming soon" outside, hoping for good luck.
