The ancestral homestead has been emptied of garbage and has never been built, or the ancestral homestead has been in disrepair for a long time. These are two concepts.
If it is just a homestead owned by ancestors, there has never been a house to live in. It doesn't matter. If you want to build a house in the future, you only need to remove some old soil and fill in new soil after removing the garbage.
If the ancestral home falls into disrepair and ruin, it will be unlucky for future generations and the rich will decline. It is also easy to be defeated by disease.
