Is Guo Guanzhiku a secret unit?

Guo Guanzhiku is not a secret-related unit. Guo Guanzhiku is an independent think tank organization, focusing on industry and policy research, consulting and information services. As far as I know, think tanks do not belong to the state secret system, and their research results are generally open and provide services to the public. Of course, the specific situation may be different because of the specific research projects or cooperative institutions involved. If there are specific details or needs, it is recommended to consult the national think tank or relevant departments to get a more accurate answer.
