Why is the house in Kaide Huafu in Ruzhou cheap?

The decoration level is not good. The property is advertised as a high-end residential area, but there are no wall tiles on the high-rise corridor. Only the villa was plastered, saying that it used a combination lock, but actually it used a mechanical key. The stairs were cement floors, and the quality was totally unacceptable. Interior painting also cuts corners, the wall skin is loose, and the apartment is poor. Now it is worthless.
