According to the wedding custom in China, the time to send wedding candy to the driver of the wedding motorcade is generally 20 minutes before departure. Before this, the groom or groom asked someone to distribute the telephone number of the staff in charge of the vehicle to the driver of each car according to the pre-planned road map, in case of running a red light or losing the car on the road, so as to contact in time. Before leaving, the groom will also set off firecrackers or flowers for all his relatives. In addition, the groom's parents and other helpers will prepare tea and "zaosheng" soup in the new house when they leave to welcome the bride and send relatives away. If you have any other questions, please consult a professional wedding planner.
