"Chinese" and "Putonghua" used to refer to Chinese classes in primary and secondary schools. As a course, "Chinese" currently means "language and writing", but some people interpret it as "language and articles" and "language and culture". The interpretation of "Yu" is not controversial, but the ambiguity lies in the polysemous word "Wen". We should create another word instead of arguing. In addition, "China people" also means "China people in Chinese", but it is an old usage.
