"Burning Bao" refers to burning wrapped paper money when worshiping ancestors. It is a form of worshiping ancestors. Yuan Mei's "Xin Qixie Shaobao": "On the half of July, people in Guangdong mostly seal and burn them with paper money, which is called Shaobao, each to worship their ancestors." Every year on the 15th day of the seventh lunar month, Japan celebrates the "Obon Bon" Festival", also known as the "Hungry Ghost Festival" (in a certain sense, the Hungry Ghost Festival belongs to Taoism, and the Bon Festival belongs to Buddhism). In some places, it is commonly known as "Ghost Festival" and "Shigu", also known as the Day of the Dead, the Seventh Festival Half a month. "Ghost Festival" is commonly known as "July 15th" (in some areas, it is the 13th or 14th day).

According to popular tradition, ancestors who pass away are released by the King of Hell for half a month in early July, so there is a custom of receiving ancestors in early July and sending them off in the middle of July. When sending gifts to ancestors, a lot of paper money is burned so that "the ancestors can enjoy it". At the same time, money paper is put into the paper envelope with the name of the person who enjoys it, and it is burned during the sacrifice, which is called "shaobao". Those who died within the year burned a new bag, and those who died more than a year ago burned an old bag. No matter whether you are rich or poor, you must prepare wine, food, and paper money to pay homage to the deceased to show your memory of your deceased ancestors. The Hungry Ghost Festival usually lasts for seven days, and there are new dead and old dead. Those who died within three years are called the newly deceased, and those who died three years ago are called the old deceased.

Superstition says that the old and new dead should go home to visit during this period. It is also said that the new and old dead come back at different times. The new dead return first, and the old dead return later. Therefore, they must be worshiped separately. The best time to burn paper money is in the dead of night. First, sprinkle lime in a few circles in the yard. It is said that the paper money will be burned in the circles so that ghosts will not dare to come and snatch it. Then burn it in piles, leaving your mouth open while burning. They have to keep saying: "So and so is here to get the money." Finally, they have to burn a pile outside the circle, saying that it is for the lonely ghosts. On the day when the deceased return home, both rich and poor must prepare a good meal to honor the deceased, which is also called "send off the deceased".
