Xi River
Wen Shi frequently went to the Xi River to fish and wash clothes for her family. On one such errand, she found a large smooth white stone along the banks of the river. She took the beautiful stone home, but later discovered that the stone was actually an egg, from which hatched five baby snakes (an alternate version says one). Wen Shi's family was poor, but Wen Shi saved the best food she had for her baby snakes and fed them by hand. As the snakes grew, they helped Wen Shi catch fish at the Xi River. The snakes were natural swimmers and became very good at catching fish.
