If op is asking about the tenure case in the US, then the answer is: no, there is no such thing in China. However, there is something like soft tenure, which is, I would say, close to the UK system.
Well, maybe similar to the UK in theoretical legal terms, but the U.K. has a specific clause in the relevant law that protects academic freedom, plus lots of laws and case law that give individuals a great deal of protection, not just in theory, but also in practice.
Academic tenure in U.S. generally means the following: When a professor is granted tenure at an academic institution, she/he is receiving a specific set of administrative and legal rights that includes the freedom to pursue any academic research without fear of repercussions or losing her/his job. Tenured faculty positions are, in some sense, seen as "jobs for life".
Really? Try pursuing research topics along the lines of those investigated by Ted Hill, Alessandro Strumia, or James Watson. See what happens to your tenure.
