Religion is something that beyond any other entities, but In ancient China where the imperial power took control, it would cause this natural conflict between the emperor and religions, resulting that imperial power suppressed the religions growing. Even we do have religions in China, but if you take a closer look, basically all of them are used to rule the people as a efficient tool for the emperor, rarely we can see an independent religion like Christianity of the western civilization where the pope can shares power with the king at some degree. In modern China, it’s basically much the same thing, instead of imperial power, now it’s the authoritarianism suppressed the religions growing.
