After the newly built house is renovated, will the old man in Jiating be there?

You can put it. From the perspective of geomantic omen, it is really not good for a new house to be a mourning hall, but it is not a big problem that the family is an old man and not an outsider. You can also think that the old man didn't live in a new house before he left, but he lived in a new house after he left and was filial to the old man. Note: The answers are for reference only. Please don't be blind and superstitious.
