According to the textual research of Wuling Treasure by Mr. Zhou from Changde, Hunan Province, the prototype of Jin Chan comes from Yanshan Mountains. In Yanshan, there was a scholar named Cao, whose original name was Haichan, and his word Zongcheng. This person is fond of talking about life and worships the learning of Huang Lao. It is said that Liu Haichan met the immortal twice, the first time he met the "founder of Zhengyang" and the second time he met Lv Zu. According to Zi Zhi Tong Jian, "When I first met the founder of Zhengyang, I got the purpose of returning the golden liquid to Dan, so I abandoned my official position and learned the Tao. Later, when he met Lv Zu, he changed his name to Xuan Ying. Re-grant the key to the elixir and flee to the south to fix the truth. " Some people say that he is the fourth ancestor of Taoism in the Northern Song Dynasty. In the first year of Yuan Dynasty to Zhengzheng, it was named after "a true gentleman understands the great Tao". Master Wu Zongshi was named "Emperor Chunfu". Some ancient books said that he was from Guangling, Hou Liang (now Xixian County, Henan Province), while others said that he was from Houliang, Shaanxi Province. It is said that one day a Taoist priest who claimed to be "true Yoko" came to visit and talked with him about the "Tao" of "one life, two lives, three lives and three things". Finally, Haichan realized the truth, abandoned his official position and took the road, and disappeared at the foot of Nanshan. After Dan became a student, he logged into Xianban and turned into a crane. The Southern Sect of Taoism regards him as the founder. Taoist Zhengyang is the founder of Li Zhong. Lv Zu refers to Lv Dongbin. Lv Dongbin is one of the legendary Eight Immortals, nicknamed "Pure Yoko". Lv Dongbin wandered the Jianghu because he failed in the imperial examination, and met Zhong Liquan, the "Zhengyangzi". Zhong Liquan gave him the Dan formula and took him to Zhong Nanshan for monasticism. Lv Dongbin should be Liu Haichan's other disciples. The golden cicada is also called Liu Hai Play Money or Liu Hai Scatter Money. Later generations divided the name Liu Haichan into two: Liu Hai and Jin Chan. These two names are perfunctory as "Liu Hai plays the golden toad".
