According to traditional customs, this is not only unfilial to the deceased, but also a great disrespect to the neighbors. Therefore, in today's deep-rooted traditional culture, the "mourning" incident is still a taboo. People who are in the "mourning period" are often unlucky in the near future. According to traditional customs, it is unlucky for someone in the family to die. If mourners visit during this period, it will bring bad luck to neighbors. Therefore, in order not to bring bad luck to the neighborhood, it is best for people who are in mourning not to visit other people's homes. You can call if you have anything, or let others come to your house to talk about things. You'd better not come to your house during the funeral.
