What are the three monsters in Hangzhou?

Lu Ciyun's Miscellaneous Notes on the Branches of the Lake in the Qing Dynasty said: "It is said that there is a demon of herring and white snake in the West Lake, and the town of Leifengta was built ..." The postscript said: "There are three monsters in the old legend of Hangzhou: the golden beach three-legged toad, the big turtle in Liufugou and the white snake in Leifengta." He added: "In Qin Long, the tortoise was hooked by Tu Jia and the toad was caught by the alchemist. However, it is impossible to know whether there is a white snake. The novelist's story about the Leifeng Tower in Bainiangzi Town is quite true. " He also said: "During the Chongzhen period, the new temple was abused for a long time, Shui Ze was withered, the mud at the bottom of the lake was cracked, the smoke from the top of the Leifeng Tower curled up, and the residents were shocked to tell that the snake had gone ..." There is also a saying in the street: Bamboo is sold as a treasure, silk as a quilt cover, and Hangzhou girls don't marry! At present, the most popular saying of "Three Monsters of the West Lake" is that "the long bridge is not long, the lonely mountain is not lonely, and the bridge is constantly broken".
