Has Taiwan disguised bunkers as ordinary-looking buildings, as Britain did during the Second World War?
Short answerThere is no explicit confirmation; the questioner is invited to walk around Taiwan without a particular concealed bunker being identified.
NotesBritain's wartime bunkers disguised as ordinary buildings provide the comparison in the question. The reply stops at an invitation to walk around Taiwan and look. That invites an inference about concealed defenses without identifying a building or confirming what it contains. The location, extent, and design of any Taiwanese bunkers remain unspecified.
