What does the fortune teller mean when he says that the granddaddy will pick it up?

What should I do to pick up my ancestors in July and a half?

When picking up ancestors, rice, vegetables, tea and wine are all put on the tray and taken out to the gate for three times to pick up ancestors.

When you bring your ancestors home, you must put some sacrificial items on the table, such as candy, biscuits, fruit and so on. Then go to an open place for a meeting, usually burning incense, burning paper, lighting candles, setting off firecrackers and meeting ancestors. In the living room, two big tables are usually put together, and then drinks are poured into the bowls on the tables, firecrackers are set off, paper is burned, candles are lit, and then ancestors are worshipped. Then everyone kowtows and adds wine every once in a while (during which adults will tell children not to touch sacrificial tables and chairs casually).

After a while, it was almost time for the wine festival, so we set off firecrackers and burned paper to end a sacrifice. During the period, drinks, tea, candy and fruit are needed for the sacrifice the night before, the morning, noon and afternoon the next day, and meals are needed for the sacrifice the next night.
