麗江古鎮又叫大研鎮，喺麗江壩中部，係中國歷史文化名城中唯一無城牆嘅古鎮，聽講係因爲麗江土司（世襲統治者）姓木，起城嗰陣好似木字加框而成“困”字嘅原因。納西族名叫“鞏本知”，“鞏本”係倉廩，“知”即係集市，所以麗江古鎮應該係倉廩集散之地。
Lijiang Ancient Town is also called Dayan Town, in the middle of Lijiang Dam, is the only ancient town without walls in China's historical and cultural city, I heard that it is because Lijiang Tusi (hereditary ruler) surname Mu, when the city is like a wooden word framed to become a collapse sieve word. The name of the Naxi people is "Gongben Zhi", "Gongben" is Cangdi, and "Know" is the market, so Lijiang Ancient Town should be the place where Cangqiao is distributed.
