握拳透掌 — “To clench one's fists so tightly that the nails pierce the palms”

During the Jin Dynasty, General Bian Hu fought heroically to defend his homeland against the rebel Su Jun. Both he and his son tragically died in battle and were buried on the battlefield.

Years later, tomb robbers broke into Bian Hu's grave. They were astonished to find his corpse still stiff, his hair at the temples white, and his complexion almost lifelike.

Most remarkably, both of his hands were clenched tightly into fists, with his fingernails having pierced through the backs of his palms. This vivid image testified to his extreme indignation and unwavering resolve even in death.
