From 《
史记·
廉颇蔺相如列传》: Warring States general Lian Po (
廉颇) resented minister Lin Xiangru (
蔺相如) for outranking him. On realizing Lin had put the state first, Lian stripped to the waist, carried thorny birch rods on his back as instruments of his own flogging, and went to Lin's gate to beg forgiveness.
