Is a person who has opened a 3 star hotel and a western restaurant self employed?

Probably not, it's a private business owner.

Self-employed is a common name for urban and rural individual industrial and commercial households, which are laborers who do not exploit others and are self-reliant within the scope permitted by our law. It is characterized by the fact that individual laborers and their family members are the mainstay, independently engage in production and business activities with their own means of production and funds, and provide commodities and services to society, which is a useful supplement to the socialist public-owned economy.

On the issue of distinguishing between private enterprises and individual businesses.

Distinguish between private enterprises and individual industrial and commercial households in the following two situations:

Private enterprises and individual industrial and commercial households that have registered with the industrial and commercial departments shall be distinguished according to their registration. Individuals receive a "business license for individual industrial and commercial households", and private enterprises receive a "business license", including private sole proprietorship companies, private limited liability companies and sole proprietorship companies.

If the tax department is a tax-paying unit of the enterprise type, it shall be regarded as an enterprise for investigation, otherwise it will be classified as a self-employed household.
