According to custom, the order of sacrifice and 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 relate to the ancestors, because the mountains have spirits but no owners, and the ancestors have owners but no spirits. It is necessary to relate to the ancestors. Feeling can better capture the aura of mountains and rivers. This is Feng Shui.
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, so that others can see it and know that there are descendants of this grave, and then kowtow and worship. Afterwards, they can sit around and have a meal and drink; they can also fly kites, or even compete with each other and engage in related activities. Women and children also need to fold some willow branches nearby and tie the removed steamed food offerings with wickers. Some people braid willow sticks into a basket shape and wear them on their heads, saying, "If you don't wear willow during Qingming Festival, you will become a yellow dog in the next life." That is: modifying the cemetery - offering incense - serving meat - toasting - paying homage - setting off cannons to say goodbye...
