The fortune-teller said that you can't be filial to others. Can I go to dinner after burial?

This question is credible or not. In some places, mourners were not allowed to visit relatives in those days, for fear that it would be unlucky to go to other people's homes. It is best not to go to other people's homes for a hundred days, so as not to violate taboos in other people's homes. Some people believe that some people don't believe this, so just make up your mind. I just want to make a suggestion.
