The first seven: a funeral custom of the Chinese nation. It is customary to think that "the first seven" refers to the seventh day after death. It is generally believed that the soul of the deceased will go home in the first seven days, and the family should prepare a meal for the soul of the deceased before it comes back, and then it must be avoided. The best way is to sleep. If you can't sleep, hide under the covers. If the soul of the deceased sees his family, it will make him miss and affect his reincarnation. It is also said that when you go home on the seventh day, your family should burn a ladder-like thing at home and let your soul follow this ladder to heaven.
