Bi Gan, surnamed Zi, was born (now in the north of Weihui City). Born in Yin (BC 1092), the seventh festival of Emperor Yi Bingzi died in BC 1029. He was loyal to the monarch and patriotic all his life, and advocated that "people should take Ming Dow and scholars should take Tao as their purpose". He is the son of Taiding, a noble merchant of Yin and Shang Dynasties. Bigan has been smart and studious since he was a child. At the age of 20, he assisted Di Yi as a high surname and was assisted by Di Xin. After more than 40 years in politics, he advocated tax reduction and share sharing, encouraged the development of agriculture and animal husbandry, advocated smelting and casting, and made Qiang Bing rich. In the last years of Shang Dynasty, Di Xin and Zhou Wang were tyrannical and dissolute, and imposed exorbitant taxes. Bi Gan sighed, "If the Lord doesn't remonstrate, he will be disloyal, and if he fears death, he will not be brave. If you don't fight, you will die, and you will be loyal. " So I went to the Star Tower to protest for three days. Asked why he relied on himself, Bi Gan said, "I rely on benevolence and righteousness, so I rely on myself." . He said angrily, "I heard that saints have seven minds and various beliefs." Then he killed Beagan and dissected his heart at the age of 63. Mrs. Bigan's wife, Gui, just got pregnant in March and was afraid of a catastrophe. She escaped and gave birth to a boy named Quan (Lin's ancestor) in Changlin Stone Room. Bigan is the ancestor of Lin. Now, Lin's descendants have made remarkable achievements in various fields.

Later, the tomb was sealed and the surname Lin was given; Wei Xiaowen Emperor Tuoba Li Hong Temple; Emperor Taizong issued letters conferring the titles of "Loyal and Liegong" and "Taishi"; For the genealogy of Lin, for the statue of Bi Gan, for the poetry of Qing Dynasty, Xuanzong of Qing Dynasty rebuilt the main hall of Bi Gan Temple. People all respect Bigan as the God of Wealth.
