Why can't the houses in Shanghai Changsi Community go up?

Why can't the houses in Shanghai Changsi Community go up? I think there are many problems here. The first is that the state is now so strict with the supervision of houses. In addition, the old and new houses in this community are also particular about the structure of the house, the regional problems of this community and the traffic problems. There is also the biggest problem, that is, buyers want to be cheaper and sellers want to be more expensive, so sellers think the house price is too cheap and buyers think the house price is too expensive, so this is a contradiction, depending on their position. Therefore, from different standpoints, we will look at the problem in different directions.
