China is different from some places. The land in China is state-owned, while in some places the land is privately owned, which means the land is owned by individuals. To put it simply, China gives you a land use certificate. , there is a time limit on it, which is equivalent to the government leasing the land belonging to the government to you for use, and there is a lease period, but in fact the house on the land is still yours. The country cannot say that after the expiration, the house and land on the land will be taken away. It will be taken back together, so generally even if your usage period has expired, you can go to the Land and Resources Bureau to apply for a new one, and they will charge some money and extend the period. In addition, it is actually very unlikely that an average house in China can stand for 70 years without being demolished. If the land in some countries is privately owned, of course the above problem does not exist, because both the land and the house belong to him.

Hope this helps you
