Taihe is far from the urban area, and it takes about an hour to take the subway from Taihe to Tianhe. In addition, there are many factories there, which are generally closed, and the rest of the rural houses are not rented in whole, so the prices are relatively cheap.
The environment in Taihe is not as good as that in the city. The wages there are also cheaper than those in the city. Generally speaking, the house is still relatively cheap.
