evidence: The Matsu Islands (馬祖列島 or mazu liedao) are a fascinating frontier region of Taiwan. [...] The Matsu Islands are formally Lienchiang County (連江縣 or lian jiang xian). They are the smallest and least populated of Taiwan’s 14 counties. Taiwanese usually refer to the islands simply as "Matsu" (媽祖). [...] Matsu Islands (along with Kinmen, another group of Taiwan-owned islands just off the coast of China) then became a major battlefront between Taiwan and China, with regular bombings between the two sides for the next decade.
