He does not belong to General 108 because:
That's the author's own ranking. There are not so many generals in the official history as 108.
Now we officially put aside novels. In the novel, I believe we all remember that Bai Sheng, a kind of vole, appeared after he filmed the birth outline, and basically there was no positive mention, that is to say, Bai Sheng's ability and contribution were very limited. We can see from Song Jiang's acceptance of woo. It seems that a man named Li detained wine and meat to arouse the anger of Liangshan heroes. Originally, a catty of wine and meat was reduced by half. In this way, the Liangshan heroes became angry from embarrassment, lost their footing, and took the opportunity to eradicate Liangshan heroes.
At this time, a water army named He Cheng came to examine Li. Li also complained to the wicked first and insulted Liangshan heroes. He Cheng killed Li in a fit of pique, but He Cheng did not evade or shirk his responsibility. He Cheng is Ruan's confidant. After hearing this, Xiaoqi said that he would save He Cheng even if he returned to Liangshan, and said that He Cheng had made great contributions in preventing the imperial army from attacking. But Song Jiang still watched He Cheng commit suicide, but Ruan was late.
It can be seen that the author does not arrange seats according to actual ability and credit. In terms of ability, Bai Sheng can't compare with He Cheng at all. As for why the author arranged this, I have to ask Mr. Shi Lao.
According to the real plough, the names of the stars of Plough 36 and Plough 72 are not the names in the water margin, so the ranking in the water margin is entirely the author's own. And in the author's opinion, classicism is bound to die.
When filming "The Outline of Birth", Chao Gai had a dream that the Big Dipper was radiant and there was a dark star nearby. After Wu Yong's dream interpretation, Classical said that Seven Stars were his three brothers Wu Yong, Gongsun Sheng, Liu Tang and Ruan Jinyong, and the dark star was Bai Sheng, the day mouse. But it turns out that dark stars are classic.
It can be seen that Chao Gai was not included in the list of 108 generals from the beginning. So even if we support classicism, we can't avoid teacher Shi's deliberate arrangement. Classical must die, otherwise 108 there will be no Bai Sheng. Classical and Bai Sheng must die before they can respond to Classical's dream and the main writing line of 108.
