Why is there so much sandpaper in Yangjiang?

There are indeed many sandpaper houses in Yangjiang City, Guangdong Province, which is inseparable from the long history of civilization here and is the embodiment of a long history and culture. But the sandpaper contract also needs to keep pace with the times, because it does not have enough legal protection. The sandpaper deed of the house is equivalent to the house sales contract, but the determination of the house property right still needs to go through the registration of the house ownership certificate with the housing management department. If it is a house with collective land, it must also be registered and certified by the land management department of state-owned resources. If there are none, it is recommended to hire a lawyer to witness the sandpaper deed and issue a "lawyer witness".
