Releasing river lanterns is one of the important folk activities that has been passed down to this day in the Lexi River Basin. Taoism in the Song Dynasty advocated that river lanterns be lit, lonely souls be saved, flames be released, and Mulian opera be performed in various places during the Zhongyuan Festival. Many poets left poems about the joyous lantern-lighting in West Lake, Hangzhou. Since then, releasing river lanterns has been held on the 15th day of the seventh lunar month and has spread with the spread of Taoism and Buddhism. During the reign of Emperor Zhenzong of Song Dynasty, the canal transportation in the Lexi River Basin began to flourish, and many temples were built along the banks, and Buddhist activities were widely spread among the people. Therefore, releasing river lanterns became one of the important folk activities in Lukong Town. During the Ming and Qing Dynasties, the Lexi River was prosperous, and boatmen and merchants hoped that the river transportation would be safe and smooth, and the residents along the river hoped for good weather and good harvests, so they released river lanterns on the 15th day of the seventh lunar month every year to help the dead souls. In addition, when a wealthy family has a funeral, they also have to release river lanterns. The purpose is to save all the hungry ghosts who have sunk into hell in the ten directions and three times for the deceased, and to perform merits and virtues so that they can ascend to the paradise early. It is said that after releasing river lanterns, there will be no more ghosts and spirits causing trouble along the river, ensuring the safety of boats and residents along the river and on both sides. After countless years, in modern times, releasing river lanterns is used by people to pray for good weather, peace and prosperity, and good fortune and well-being.
