2. The usual procedure for sweeping tombs during the Qingming Festival
The order of sweeping is to first sweep the tomb, that is, clean the cemetery.
The second is sacrifice. This procedure is very important. One is to express grief, and the other is to commune with the ancestors.
When sweeping the tomb, people bring wine, food, fruits, paper money and other items to the cemetery, offer the food in front of the tomb of their relatives, burn the paper money, put new soil on the tomb, trim the tomb, and break a few new green branches. Insert it on the grave, and press some paper money on it to let others see it and know that there are descendants of this grave, and then kowtow to worship.
