"The Theory of Bones" says that "4678 is unlucky, flowers change into osmanthus fragrance, and husband and wife grow old together." Does this mean that this person will remarry at 4678?

The general idea is that this person may not be successful when he is young, but he will be lucky when he is middle-aged, but if he has no children, he is doomed to recognize an adopted son, or adopt a son from the clan, or get a good son-in-law at home. Although I have no children, I will have a happy marriage, loving husband and wife, growing old together, and full of children and grandchildren.
