The problem is you literally cannot trust anything positive that comes out of China. This isn't jingoism, western countries have their own issues, but China is a country set up only for rewarding positive results and severely punishing negative or even neutral results. Having worked from China in numerous jobs, a good chunk of the useful information they have is a liability as it's most likely stolen from elsewhere. To be clear this has absolutely nothing to do with the individual person, but with the risk/reward structure that exists in mainland China.
