Why must Qingming worship the mountains? How did Qingming come from?

Tomb-Sweeping Day is the only folk festival in China with solar terms and festivals. Tomb-Sweeping Day, an old Shenzhen native, went up the mountain to worship his ancestors. His name is "worship the mountain". According to local customs, Tomb-Sweeping Day mostly worships ancestors with family style, and the Double Ninth Festival is a family style (whole village or full name) to worship ancestors; Of course, there are also some villagers who go to worship the mountains during the Mid-Autumn Festival, such as a few villages in Pingshan, Longgang and Pingdi. Before worshipping the mountain, I went to the restaurant the next day and ordered a roast suckling pig, and prepared sacrifices such as fruit, tea, wine, rice, candy, "chicken manure vine", mugwort cake, biscuits, incense sticks, firecrackers, gold and silver paper money. The next morning, dozens of people from the whole family or brothers took hoes and shovels to weed the graves and cultivate the graves of their ancestors. In front of their tombstones, sacrifices, tea and wine were placed, and the elders began to avoid their descendants. Everyone lit three incense sticks, bowed down to their ancestors and said, "We have come to see you and brought you your favorite food and clothes. I hope our ancestors will bless our children. " Then, burn paper, renew tea, renew wine and set off firecrackers. In the past, after the traditional mountain worship, because of the inconvenient transportation, we had to solve the lunch on the mountain. Dig a hole in the mountain to make a stove, collect firewood and cook, which is called "eating the mountain". Now that the transportation is convenient, I will go home for dinner soon. When I go home, I leave other sacrifices and only bring back roast suckling pigs and apples for my brothers to eat, following the custom of "sharing Taigong pork" in the past; It is said that the roast suckling pig in Baishan will be blessed by its ancestors after eating, and everything will be smooth and safe. On the way, everyone also ate one or two candies to worship the mountains, reminiscing about the care their loved ones gave to future generations before their death, and cherishing the happy life in their own homes now. The local people attach great importance to the worship of this mountain, and compatriots from Hong Kong, Macao and Taiwan, overseas Chinese and relatives have all rushed back to worship. Whether there is new soil on the tomb determines whether the owner of the tomb has children. There are "children and grandchildren in the countryside, hanging Qingming; No children, light graves. " As the saying goes, "If you don't worship your ancestors in Qingming Festival, you will become a pig and dog when you die", and the common people's mantra also says, "Add more flowers and you can worship the mountains." It means to have a son, and when he is old (dead), future generations will worship the mountain. Therefore, the people spontaneously formed a custom pressure. People pay homage to their ancestors by sweeping graves, and at the same time, they deeply feel that future generations will prosper. It is said that ancestors living in graves are related to the prosperity of future generations, and the prosperity of future generations can ensure the safety of ancestors and the continuation of incense. Therefore, the ancestral grave is not only the root of life, but also the knot of emotion. Of course, now is a new era, customs are changeable, and there are many innovations while worshipping mountains and ancestors.
