history

Laixi river originates from Dazu, Chongqing, flows through Rongchang, Chongqing and Luxian County, Sichuan, and joins Tuojiang River in Hushi Town, Longmatan district. Laixi river was called laipo River in Tang and Song dynasties. It was the main transportation channel from Dazu to Rongchang and from Rongchang to Luzhou in ancient times. But there were some stone beaches every other section of the river to block the navigation, so the river was navigable section by section. On these stone beaches, the navigation was blocked, and the goods had to be transshipped here to continue the navigation.

Legend of wangniangtan

It is said that a long time ago, there lived a family by the Laixi River in Southwest China. There are only mother and son in the family. The mother is blind, so she relies on her son Nie Lang to help others herd cattle and gather firewood for a living.

One day, Nie Lang was cutting cattle grass on the hillside. He found a nest of cattle grass called baergan. It was tender and luxuriant. Once cut, it was a big back. The next day Nie Lang went up the slope to mow the grass. He was very happy to see that the cow grass had grown up again and cut his back home. On the third day, he went up the slope to mow the grass, and the nest grew again. He felt strange and thought: why don't I dig it home and plant it at the door of the house, so that I can take care of my blind mother and cut grass to feed cattle. So he took a hoe and dug up the nest of cattle grass. When he dug out the nest of cattle grass, he found a shining bead under the grass root. He took the grass back and planted it behind the house, and it never grew again. However, when he put the bead in the bag with money, there was a lot more money in the bag. When he put the beads in the jar with rice, the rice in the jar would "grow" all over the jar the next day. In this way, his family's life is getting better and better day by day.

Before long, when the local rich man knew about it, he broke into his house with a group of servants and said that his rice and money had been stolen. He wanted to search his house to see if he had stolen it. Nie Lang was afraid that the rich man would snatch his treasure. He threw it into his mouth, but he didn't notice and swallowed it. The rich man searched for a long time, but he didn't find anything. He just robbed his family of rice. In the evening, Nie Lang felt very thirsty. His mother scooped bowl after bowl, but she couldn't quench his thirst, so she told him to drink in the water tank, and he took the water out of the tank
