Where have you heard this about Chinese culture in particular? I’ve only heard of such a trait in reading Robert Altemeyer’s book The Authoritarians, where it is described as a common trait of right wing authoritarians, who appear to not be very good about comparing the various ideas they have together to see if they are contradictory. Altemeyer describes it as the result of an upbringing that emphasizes loyalty and submission and that posits that truth is something that comes from an authority figure, rather than something that can be derived from available facts for oneself. But I think that applying that critique to an entire country seems harsh, without evidence.
