There are roughly three forms of ancestor worship:
First, it is a common way, that is, it is held in the ancestral grave (usually the graveyard in the village), commonly known as "going to the grave". The time is mainly the anniversary of death and traditional major festivals (except Mid-Autumn Festival), such as New Year's Eve, Tomb-Sweeping Day, Mid-Autumn Festival (July 15), 10/day, June 1 day, etc. The men in the family bring sacrificial incense paper to the grave, place sacrifices and water wine, then burn paper, burn incense, drink a libation, salute, and press paper on the grave.
The second way is family sacrifice, that is, not going to the grave, or going to the grave at the same time. The memorial tablet or genealogy map with direct ancestors written on it is enshrined in the main hall or "home temple" for the whole family or the whole people to sacrifice together. The ceremony at home is called "Inviting Family Hall", which is very grand. In our village, the sacrifice spectrum is presided over by the oldest person in the family, and it is usually carried out at the same time as the continuation spectrum during the Chinese New Year. In recent decades, due to the implementation of cremation, cemeteries have become common, and grave sweeping is also carried out in cemeteries.
There is also a kind of "remote sacrifice", also called "please". Because of the bad weather, I can't go out or go to the cemetery in person, so I set up sacrifices at home or near the field, incense to the ancestral cemetery in my hometown, and ask my ancestors to enjoy the sacrifices.
History of going to the grave:
The more common way is to hold it in the place where the ancestors were buried, commonly known as going to the grave. Time is mainly the anniversary of death and traditional major festivals, such as New Year's Eve, Tomb-Sweeping Day, Mid-Autumn Festival, October 1st, June 1st, etc. The men at home bring sacrifices and incense paper to the grave, place sacrifices and water wine, then burn paper, burn incense, drink libation and salute, and press the grave paper in the meantime. The custom of going to the grave is the most solemn, especially in Tomb-Sweeping Day. The morning before, we would add soil to the graves of our ancestors to show the prosperity of our family.
Most sons of rural families go to the grave when they get married, which means telling their ancestors that their sons are married and have a large population. In addition, at the dawn of the seventh day after death, the family went to the grave to pay homage and mourn, which was called the "seventh base". Then it will be held every seven days. Generally, it will be finished in May and July, and some will arrive in July and July. On the100th day after death, relatives and children prepare sacrifices to pay homage, which is called Baixiang. In the past, some people put cash cows, cartons and paper cabinets on graves and burned only some paper money.
