First, buy some fruits, meat, cigarettes and wine, all of which are food. There are only firecrackers with small incense. Note that when you go, if no one drinks cooked meat, you should also bring a few small cups to pour wine and a live chicken (such as brothers and parents). The first thing to do when you get to the grave is to kill the chicken (save money), put the fruit, meat and cigarettes in the good wine, and then set off. Point-and-line incense, three yuan for each tomb, burning paper and point-and-line incense in the ground, that is, pouring some wine directly on the ground on the right side of each tomb. At this time, guns will be fired (guns will be fired when inserting tomb money, there is no special regulation), and then everyone will bow down, and everyone will bow down at least three times. It is best to bow down a few times to show sincerity. (No order required) You can leave in a few minutes.

This is my experience, I hope I can help you.
