Jiang Shi and his wife were devoted to his mother, who preferred river water to well water for drinking. The river was far away, but his wife hiked there for fresh water and fish for his mother. One day a spring gushed up right behind their houseā€”its fresh flavor just like the river, with carp leaping from the spring. From then on, the couple had no farther to go than a few steps for fish and water.
