(2) Some people will move their graves in Tomb-Sweeping Day, so it must be remembered that any new grave cannot be moved as long as it has been buried for less than one year. If you move and bury within one year, it will create a home.
(3) It is very important to establish a monument and make a biography. Every grave has an orientation, so if a monument is erected in front of the grave, it is easy for future generations not to know the mountain and orientation of the grave, resulting in inconsistency. The inconsistency between the new tomb and the ancestral tomb is called "the ancestors are broken, the descendants are unfilial, full of difficulties, leaving their homes, or the population is gradually decreasing". (Of course, this point is discussed in ancient books, so don't be too persistent. )
