To Chinese people, maybe this sign looks normal. But, as a former Japanese student, I found this sign very amusing.
In every language I know of that has borrowed from the Chinese writing system, 手 means hand and 紙 means paper. Many many words made out of multiple characters have the same meanings in Japanese as they do in Chinese. This case is an exception. 手紙 means “letter” in Japanese, but in the Chinese sign above, it means “toilet paper”… a nasty false cognate if I’ve ever seen one! Does anybody know what 手紙 means in Korean?
