Is it legal to change an old office building into a hotel?

Hello, dear, this is illegal. The property right of the old office building is office and cannot be used for business. Therefore, the property of the old office building cannot be changed into a hotel. This is an ordinary office building with clear policies. Before the project is approved, it is necessary to submit a clear plan in the Land and Resources Bureau in advance, such as business, apartment, office building, residence, etc. Once the relevant government parts are approved by wholesale, it is difficult to replace the later property rights and uses.
