Introduction to Longshan: According to legend, in the early years of the Northern Song Dynasty, there was a little black dragon born to Wang, the wife of Li named Li, at the foot of Longshan. The little black dragon was so painful that its tail was cut off by its father, so it clawed its way out of the dragon pond on the top of the mountain. He flew to Heilongjiang and defeated the big white dragon that caused disasters and brought benefits to the people. People called this black dragon "Tailless Old Li" and respected him very much. The tailless old Li Xingyun is extremely effective in spreading rain. If there is a drought, rain will always come and the blessings will spread widely. The Empress Dowager Cixi personally wrote a plaque reading "Zezhou Zhuangwu", and Emperor Guangxu conferred the title of "King of Jiujiang" on her. According to records, "taking dragon tablets to pray for rain" has been popular since the Ming and Qing Dynasties. In the Qilu land of Qilu in the Qing Dynasty, there were 107 temples with "dragon gods" in ten prefectures and ten prefectures, 7 of which were dedicated to praying for rain. , only the Dragon King Temple in Tianjingshan has a unique dragon tablet in the pool, with a total of 63 metal dragon tablets stored in it.
