How about opening a curtain shop in the community?
It depends on when your community was built. If it is newly built, and many have not moved in, the market is still good. If it is already a mature community, the market prospect is not good. Because the community sells a fixed population, few floating people come to you to buy it, but everyone in the community has curtains. Who will buy it? Unless it is very distinctive, it is best to resell some daily necessities. Curtains are not a necessity.
