Can I buy a house in Nantong Development Zone and attend primary schools in Xiaohai and Zhu Hang?

Yes, it can be bought, linked to Sutong Bridge and Industrial Development Zone. It is very likely that an industrial new city will be built in a few years, so there is more room for appreciation. However, due to the further tightening of the national housing policy, the increase may be slower. So if you have money, you can consider buying it, and renting it is more cost-effective.
