"Chang'an (/\u02C8t\u0283\u0251\u02D0\u014B\u02C8\u0251\u02D0n/, About this sound listen ) (simplified Chinese: \u957F\u5B89; traditional Chinese: \u9577\u5B89; pinyin: Ch\u00E1ng'\u0101n; Wade\u2013Giles: Ch'ang-an) is an ancient capital of more than ten dynasties in Chinese history, today known as Xi'an. Chang'an means \"Perpetual Peace\" in Classical Chinese. During the short-lived Xin dynasty, the city was renamed \"Constant Peace\" (Chinese: \u5E38\u5B89; pinyin: Ch\u00E1ng'\u0101n); yet after its fall in AD 23, the old name was restored."@en .
