Wu Zhan lived near Jingxi, where there was a particularly clear and limpid spring on which the population relied. Zhan protected it with a bamboo fence, to keep out the dirt. One day, Wu was by the side of the spring when he caught a white snail and put it in an earthen jar. Whenever he came in from outside, he found food and drink already prepared in his kitchen, and he was shocked and astonished. One day he managed to peep in, and saw a woman emerge from the shell and take up a cooking knife. Wu hurried in towards her. She was unable to return to her shell, and told him truthfully: “I am a spring spirit. Because the gentleman respected and protected my source, and because it is known that the gentleman is a widower, I was commanded to prepare food for the gentleman. If the gentleman eats my food, he will attain the Way.” When her speech was finished she vanished.
