雁门关
Yanmen Pass, sometimes translated in English to Wild Goose Pass or Wildgoose Gate, is named after the wild geese who migrate through the area. "Yànménguān" is the pinyin romanization of the Mandarin pronunciation of the Chinese placename written as or in traditional characters and as in the simplified characters now used in mainland China. The same name was formerly written as "Yen-mên-kuan" in the Wade-Giles system and as Yenmen Pass by the Chinese Post Office.
