On the wedding day, how many cars are usually prepared for the car behind the main car? (The car photographed by camera doesn't count.)

actually, this is based on personal conditions. The more, the better. If you have many friends, you can borrow them. If your wife values this and you don't have many friends who have cars, you can post on some carpooling websites and call the car followers to indicate what kind of car you want and what color. Many private car owners are willing to provide this service. The current market seems to be around 4 yuan (depending on the number of kilometers and cars, you should be able to find intermediate cars such as Passat and Accord at this price, and it takes 4 hours for 1 kilometers). I think 6-8 cars will be enough, otherwise it will be difficult to deploy and park.
