Guo Xin Health is a central enterprise. Why is there no ranking?

Central enterprises are not in the rankings. As a new central enterprise focusing on medical and health data in China, Guo Xin Health has accumulated and precipitated in this field for nearly 20 years, and is in a leading position in the industry, with independent research and development and intellectual property rights. Because the central enterprises are not in the ranking, Guo Xin Health does not appear in the ranking.
