The ritual of praying for rain with grass dragons is said to have originated from a drought in the Tang Dynasty. It is said that Han Xiangzi, one of the "Eight Immortals", was from Yexie Tingjing Village. In order to relieve the drought in his hometown, he summoned the "Blue Dragon" from the East China Sea to bring heavy rain, which brought a long-term rain to both sides of the Yexie Yantietang. In order to repay Han Xiangzi's kindness of "playing the flute to summon the dragon", the local people renamed the Yantietang "Longquan Port" (790 AD in the Zhenyuan Period of the Tang Dynasty), which is still used today. Every year, the villagers use golden straw to make a grass dragon with four sections of four feet, a cow's head, a tiger's mouth, a deer's horn, a snake's body, an eagle's claw, and a phoenix's tail, praying for good weather and good harvests. Since then, praying for rain with grass dragons has become a folk custom in Yexie and has affected the surrounding areas. In the process of inheritance, folk dances such as grass dragon dance, rolling lantern dance, and Shuizu dance have been formed. The ceremony is held on the 13th day of the fifth lunar month and the 13th day of the ninth lunar month during the local "Guan Di Temple Fair". The "divine flute (symbolizing Han Xiangzi)" and the tablet of "Qinglong Wang" are enshrined. It is divided into seven procedures, including "praying", "moving clouds", "seeking rain", "taking water", "rainfall", "rolling dragon", and "returning to the palace". It is solemn and grand, and is a collective sacrificial activity in the village. The offerings are all from the local area, such as old rice, wheat, beans, melons, carp, etc., expressing the simple and strong gratitude of the local farmers. In the "rainfall" ceremony, two village girls continuously splashed the water in the basin to the audience, symbolizing "splashing dragon water". The audience scrambled to let the village girls splash water, which was a prayer for the continuation of the collective life of the village. This dragon-worshipping rain-seeking ceremony, which is close to the ancient original ecology, has been passed down for nearly a thousand years because of its cultural function of integrating the collective strength of the village, and has bred distinctive folk music and dance. In 1950, the ceremony was held in the area to relieve the drought. Later, it was interrupted due to the decline of the temple fair. It has been restored in recent years.
