Blind Old Xu was a veteran of Northern Liang. After he went blind, he accidentally failed to avoid the hooves of a rich kid's steed in the downtown area. He was trampled, crippled, then saved by Xu Fengnian. Although Old Xu had a broken leg, an officer came and said they would give him a tael of silver every month. Old Xu collected the silver apprehensively for half a year before plucking up the courage to ask the officer. The officer told him it was a new rule of the Northern Liang army to treat veterans well.
