Liang Shanshui is 800 miles away from Fiona Fang, with rich products and steep terrain. From the Wang Lun era to the Sung River era, we have never seen any territorial expansion, and sooner or later, we will not leave the circle of Liangshan Shui Bo.
Although Song Jiang also attacked other cities, they all attacked and did not occupy them. For example, borrowing food from Dongping and Dongchangfu is actually robbing food. Retreat after looting, did not occupy this place, changed the dynasty, and set up a fake post.
The other three coaches are different. Tian hu occupies 56 counties in 5 states and Fang La occupies 25 counties in 8 states. Wang Qing's territory is even larger, reaching 86 counties in eight states. Compared with these, Liangshan Shui Bo is simply a park.
There are far more troops in Sankou than in Songjiang, and Fang La has as many as 300,000 troops. This is beyond Song Jiang's compare.
Second, Liangshan did not establish political power, and the level of heroes was different from that of officials. The other three kou copied the regime system of the imperial court, claiming the title of king and setting up false posts, and also copied the practice of Zhao Guanjia to build palaces and maintain a large number of concubines.
Song Jiang managed Liangshan for many years or stayed in the "Mountain King" class. At most, I built several welfare homes for my brothers, and I didn't even marry my wife, let alone raise a group of nuns in the harem. He is not as ambitious as Sankou and wants to get rid of the addiction of being an "emperor" in the chaos. He doesn't even want to bring down Emperor Zhao, but he still has the idea of "loyalty to the monarch" in his bones. Of course, he also knows that he doesn't have the strength, and he has a correct understanding and evaluation of himself. He won't be self-inflated just because Li Kui jy shouted, "You AE can be the Emperor of DaSong".
It is precisely because of his limited strength that Song Jiang planned a road to harness Liangshan, unlike Sankou and the imperial court, which have been challenging and dying to the end.
