From Du Fu's (
杜甫, Tang dynasty)
《绝句》:
两个黄鹂鸣翠柳,
一行白鹭上青天。
窗含西岭千秋雪,
门泊东吴万里船 - 'Two yellow orioles sing among green willows; a row of white egrets climbs the azure sky. My window frames the thousand-year snows of the western ridge; at my gate are moored ships from Wu, ten thousand li away.' Written in Chengdu at Du Fu's thatched cottage -
西岭 refers to the snowy peaks west of the city.
