Every elementary student can recite 'two yellow orioles sing in the green willows.'
Tips
history
Opening line of Du Fu's (杜甫, Tang) 《绝句·两个黄鹂鸣翠柳》, written in Chengdu after the An Lushan rebellion: 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 in the green willows; a line of egrets climbs the blue sky. My window frames the west range's thousand-year snow; my gate moors the ten-thousand-li boat from Eastern Wu.) A cornerstone of Chinese primary-school poetry.
usage
黄鹂 (huánglí) = yellow/black-naped oriole. The 个 measure word for birds here is unusual in modern usage (usually 只), preserved as Tang-era vernacular.
