What kind of land does Hainan need to build hotels and other businesses? If the nature is other, how to change it into legal commercial land?

You need the approval document from Hainan Provincial State Sports Planning Bureau to change the nature of land and commercial land. With the consent of the local county and municipal government development and reform commission, you can apply to the provincial development and reform commission for approval documents to change the nature of land. Generally, the approval document of the provincial development and reform commission can be completed within one month. The government doesn't spend money on writing or buying things.
