悬梁刺股
“头悬梁，锥刺股”的略语。字面意思是把头发拴在屋梁上，用锥子扎大腿。来源于古人刻苦读书的故事。今天，这种有损身体健康的极端方式已不再提倡，但其刻苦求知的精神仍广为称颂。
Tie One's Hair on the House Beam and Jab One's Side with an Awl to Keep Oneself from Falling Asleep while Studying
The term literally means to tie one's hair on the house beam and jab one's side with an awl. The idiom comes from the ancient story about how assiduously people studied. Today, this kind of extreme measures which are physically harmful are no longer encouraged. However, this kind of assiduous spirit in the pursuit of knowledge is still highly lauded.
引 例
头悬梁，锥刺股。彼不教，自勤苦。（《三字经》）（孙敬读书时把头发拴在屋梁上，以免打瞌睡；苏秦读书，每到困倦时就用锥子扎大腿。他们不用别人督促，而是自觉地勤奋苦读。）
Sun Jing tied his hair to a roof beam to prevent himself from falling asleep while reading; Su Qin jabbed at his own thigh with an awl to keep himself from dozing off while studying. They both studied hard on their own initiative without other's supervision. (Three-character Classic)
