Getting on and getting off is a custom in some parts of northern China. It means that when the groom goes to the bride's home on the wedding day, he needs to give a red envelope when he takes the bride into the wedding car, and another red envelope when he takes the bride out of the wedding car. The amount of red envelopes is not specified, this custom is just lucky, the amount is less than one thousand, more than thousands to tens of thousands, depending on the economic conditions of the man.
