Do the parents have to go out to pick up the bride?

This place has different customs, so you should have them all. In northeast China, the man's parents will go out to meet him and help the bride get off the wedding car, and then the bride will bring flowers to the old woman and the old man, and the family of four will take pictures or something. But I went to Hebei to attend my colleague's wedding, and her old woman went out to meet her, but without these procedures, she just went in with relatives and friends. The custom in your place is to ask the old people at home.
