Is the house in Intercontinental Health City commercial or residential? How many years of property rights?

Intercontinental Health is a commercial project with 40 years of property rights. The so-called "commercial" projects refer to houses built on commercial land, which are divided into two types. A house built on civil land is a residential project with a property right of 70 years, and a house built on commercial land is a "commercial" project with a property right of 40 years. Property right refers to the right to use land, which belongs to the state and not to individuals. Buying a house means buying two rights, 1 is the property right, that is, the property right certificate, and the second is the land use right, which has a time limit.
