A restaurant run by an individual is considered a business or a business

Of course, it is an enterprise or an industrial and commercial business, just register and know! Public institutions serve government agencies.

Enterprises generally refer to legal persons or other social and economic organizations that use various factors of production (land, labor, capital, technology and entrepreneurial talents, etc.) to provide goods or services to the market for the purpose of making profits, and implement independent operation, self-responsibility for profits and losses, and independent accounting.

Self-employed people are personal businesses.

My understanding is that career is a paradigm and has a wide range of meanings. Revolution can also be called a cause, and if you don't believe it, you can watch anti-Japanese dramas. The company's regulations should be constant in relation to the number of assets, the scale of production, and so on.

Public institutions belong to the state establishment, how can you personally run a restaurant be considered a career?!
