What does it mean to live from July 17 to July 7 after the death of the old man?

People start from death as a day. For example, the old man left today, so today is the first day, overnight is the second day, and every seven days is a "seven". Generally speaking, the first seven funerals [the elderly must stay at home for seven days, and special circumstances can be advanced or postponed, but they must be decided after Mr. Yin and Yang see them], which means that after our mother gives birth to us, we will do housework by ourselves within seven days. On the whole, Erqi is nothing special. Speaking of Sanqi, the family will get together to cherish the merits of the elderly. It won't be four or seven. On May 7th, that is, 5*7=35 days, which is the "full moon" when we were born, we also need to get together and live a good life. Six or seven, but ... after July 7, everyone will cry in the cemetery, because after July 7, our mourning period will expire, so there is no need to celebrate the anniversary of July 7. After July 7th, it will be a century-old taboo and an anniversary taboo.
