The whole poem: 古人学问无遗力，少壮工夫老始成。纸上得来终觉浅，绝知此事要躬行。 'The ancients spared no effort in learning; work begun in youth bears fruit only in old age. What comes from paper always feels shallow; to really know a thing you must do it yourself.'
history
陆游 wrote it late in life for his youngest son, 子聿. The rare character 聿 reads yù.
