Kiss, also known as tail, fish-shaped dragon According to legend, it was introduced from India with Buddhism around the Northern and Southern Dynasties. It is something under the rain god in Buddhist scriptures, which can put out fires. So the kiss was changed, so it was placed at both ends of the roof to eliminate disasters and put out fires. Laojiu, a dragon-shaped spiny-swallowing beast, has a wide mouth and a rough mouth, which is easy to swallow all his life. The dragon heads at both ends of the temple ridge are his portraits. "Taiping Yu Lan" has the following description: "After the disaster of the Liang Temple in the Han Dynasty, the witch said,' There are fish in the sea, and the tail is like a owl, and the waves are like rain', so it is like a tail and Tired Ofthe Fire is auspicious." The "witch" mentioned in the article is the alchemist and the "fishbone" is the predecessor of kissing. Kissing is water-based and an evil thing to avoid fire.
