At present, there is no unified concept of big health, and various pharmaceutical companies and consulting institutions are using their own standards to measure the big health industry. It is generally believed that all industries related to human health can be included in the category of big health industries, and all kinds of classifications should be integrated. Personally, I think it should be divided into the following aspects:

First, the pharmaceutical industry. Big health industry is the most basic industry, which can be divided into two parts: pharmaceutical industry and pharmaceutical business. The pharmaceutical industry can be divided into nine sub-categories, which are familiar to everyone, including raw material medicine manufacturing, chemical medicine manufacturing, Chinese herbal pieces processing (including Chinese medicine formula granules), Chinese patent medicine manufacturing, biological products manufacturing and drug sales manufacturing, medical equipment manufacturing, pharmaceutical machinery manufacturing, sanitary materials and medical supplies manufacturing, and generally include distribution, logistics and medical research and development services.

Second, the medical service industry. Including hospitals, clinics and other traditional medical services.

Third, health care industry. Including food, health food, nutritional supplements and other sub-industries.

Fourth, the health management industry. Mainly the health management and service industry extended from the concept of "disease prevention". Including health examination, health consultation, rehabilitation, health care and old-age care services.

Fifth, the health care industry. In the health care industry, the concept of great health will be further extended to beauty, entertainment, personal care products production and sales.

Sixth, other health-related industries. Including medical tourism, pension real estate, health insurance, etc.
