A clear spring from Longdongzi in the back of Sanxi Temple, a Millennium ancient temple about one kilometer away from Lutang Hot Spring, passes through the temple, forming "Longdong Shenshui around Sanxi"; The "Three Arrows Water" under Woniu Lake, about one kilometer away from Sanxi Temple, is the source of wading river, the main river among the four major rivers in Mianzhu. Mianzhu County Records records that Yang Xiu, king of Shu, shot water with three arrows. Next to Sanjian Water, there is a "Inscription on Lingyuan Bridge" made in the 11th year of Hongzhi in Daming, which reads "... It is said that the Duke of Shu visited the tomb of this army, and the three springs were filled with water ..." According to folklore, Meng Changjun, the emperor of the later Shu Dynasty, shot water with three arrows to solve the drought in the middle of Shu. Because the secret was leaked, the old monk's skin was swollen and painful. He went to Sanxi Temple with the empress Mrs. Huarui. The old monk decocted the yin water without the sun in Longdongzi, added the yang water without the sun at the exit, and decocted it with herbs, which cured Meng Changjun, king of Shu, and Huarui, queen of Shu. Later, Meng Changxin rebuilt Sanxi Temple and the Summer Palace (now the living room). Miao Kong once told Meng Chang a story. "After the emperor shot three arrows, three arrows of water poured out from three streams of clear water. Due to the vibration of arrows, the Longdongzi of Sanxi Temple spouted a clear spring. This water is related to the Jade Princess, an ancient country. It is said that after her death, the Jade Emperor named her a fairy. One year, there was a drought in the middle of Sichuan. Princess Yu saw the suffering of Mianzhu in her hometown in the sky and couldn't help crying. Tears spilled on Mianzhu's land and turned into more than 100 springs, saving the people. The tears spilled on the ground are deep and shallow, and the shallow spring water immediately gushes out, goes deep underground and then erupts. The water of three arrows, the water of Longdongzi in Sanxi Temple, is the fountain of tears for Yu Fei, benefiting the people. "

The geographical locations of Lutang Hot Spring, Sanxi Temple Longdong Shenshui and Sanjianshui are wonderfully formed into an isosceles triangle, which can be described as "the three springs stand upright and support each other." One hot spring, two cold springs, this is a gift from nature. Lutang Hot Spring is a hot spring where Princess Jade's tears drip into the ground. Coincidentally, R&F Tai Investment Development Co., Ltd. has invested heavily in development, and the first phase of the project is coming to an end and will be officially opened.
