The young pine resents it is not yet a thousand feet; the vicious bamboo ought to be cut down by the ten thousand.
Tips
history
From 杜甫's (Tang dynasty) 《将赴成都草堂途中有作,先寄严郑公五首》 its fourth: 新松恨不高千尺,恶竹应须斩万竿 - 'The young pine resents it is not yet a thousand feet tall; the vicious bamboo ought to be cut down by the ten thousand.' The pine stands for worthy talent deserving quick growth; the bamboo, for rank weeds of corruption.
usage
Almost always quoted together with 恶竹应须斩万竿 - the paired wish: promote the worthy fast, cut down the corrupt en masse. 恨 here means 'to regret / resent' (not 'hate'), a classical usage.
