Can nine rural self-built houses in the north be opened?

Nine rural self-built houses in the north can be opened. The walls between the nine northern houses in rural self-built houses are basically not load-bearing walls, and the safety of the houses will not be affected if they are smashed. If the Jiubei house built in rural areas is opened, the space area will be very large, so all the Jiubei houses built in rural areas can be opened.
