Who is the blue faced sage in Water Margin? Why is it only once?

The blue-faced sage is not a human being but a god, the god of prison, as for the reason why it only appears once, it should be that Liangshan 108 will only worship the god of prison when Song Jiang is a more disciplined person who enters the prison, and other people estimate that they will not take this matter to heart when they enter the prison, it is difficult to imagine that Li Kui took a double-plate axe to worship the god of prison, Lu Zhishen could not even uproot the statue of the blue-faced sage directly, as for the historical prototype of the blue-faced sage, there are many historical prototypes. <>

First, the founder of the prison First of all, most people now think that the god of prison is Gaotao, because in ancient times, this ancestor created criminal law and prison, it can be said that he is the founder of prison, and Cangjie is called the god of words, Gaotao is also known as the god of prison, and what is more convincing is that it is recorded in the book that Gaotao's ** is like a cyan melon, so it is absolutely understandable that he is called a blue-faced sage. <>

Second, Xiao Xiangguo's temple, but because of the passage of time, the god of prison has also changed, so the blue-faced sage in "Water Margin" is actually not Gaotao but Xiao He, the reason why Xiao He is called the god of prison has a lot to do with the work he does, in the Han Dynasty he was also responsible for this aspect of the law, and also wrote a code "Nine Chapters of Law", which made a great contribution to the reform and construction of the prison. Therefore, the blue-faced sage in the Ming Dynasty** basically refers to Xiao He, and because the time is close, there is still Xiao He's temple, but because the characters have changed and the image has not changed, the god of prison is still green-faced. <>

3. The legend of Ya Ye The last person is called "Ya Ye", which is not a particularly famous figure in history, and is recorded as an ordinary jailer, but he has a legend that there is a legend that many prisoners held by Ya Ye during the holidays one year wanted to go out to accompany their families, and Ya Ye let them out, and believed that they could come back, and finally Ya Ye did succeed, and these prisoners came back, because of this he was called the prison god by the prisoners.

It should be the prison god Gaotao. Because Song Jiang was sentenced to beheading after only entering prison once, he went to worship the blue-faced sage before he died, and then drank the severed head wine.

refers to the god of prison, because Song Jiang is the kind of person who is more disciplined, and worshipping the god of prison is also the need of that storyline.

The "green-faced sage" in the water margin refers to the god of prison, there are many "god of prison" in ancient China, and the current mainstream view is that the "blue-faced sage" worshiped by Song Jiang and Dai Zong is Gaotao. The reason why it only appears once is that only that episode requires worshipping the Blue-Faced Sage.

It is because the blue-faced sage is Song Jiang's confidant, and he can be regarded as Song Jiang's Bole, so Song Jiang will worship.
