Emphasize one point.
Going to the environmental protection agency is a sewage permit. In order to assess the environment of the hotel's oil fume emission, it is necessary to install an oil fume purifier to make the oil fume emitted by the hotel conform to the relevant provisions in the Emission Standard for Cooking Oil Fume, and effectively prevent the oil fume from polluting other people's living environment. When you go to the industrial and commercial bureau to apply for a business license, you will be required to implement the provisions on neighboring relations in the Privilege Law of People's Republic of China (PRC), that is, you will be issued a license only after obtaining the consent of your neighbors who may be polluted by oil fumes. However, if your hotel is small, you may only be required to implement effective rectification measures to prevent oil smoke pollution. If the oil fume emission causes pollution, it will be complained or even prosecuted.
