False Friend: “Authenticity” (Personal): Do not use `真伪` to describe a person's character in the sense of being “true to oneself.” For that, you would use words like
诚实 (chéngshí - honest) or
真实 (zhēnshí - true, real, not putting on a front). `真伪` is reserved for the factual genuineness of things, statements, or information.
