How should the old man die on July 7?

There are the first seven, and the seventh day from the date of death is called the first seven. It burns every seven days for seven weeks. Burn in front of the grave or coffin, prepare offerings, incense, wax, paper and rice with water (rice with water means: half a bowl of rice, add some water to each tribute, burn paper candles and pour them in front of the grave). Of course, the customs of every place are different, but 77 years is similar.
