Su Dongpo actually recommended Gao Qiu.

             The Water Margin Characters in a Nutshell (Fifteenth)

 1. At a time when he had been defeated three times in row in his attempts to suppress the Liangshan stronghold, Gao Qiu was still invited by Song Jiang, the leader of the Liangshan bandits, a distinguished guest to a banquet, where he was shown the courtesy of a knee-bowing ceremony. The greatest disrespect he suffered was nothing more than a fall on a cushion and a few gulps of water in the marsh. What's the big deal?

 2. Yang Zhi, who was unjustly scolded by him and Lin Chong, whose family was ruined by his atrocities, were both present at the banquet, but they could do nothing about it. They had to endure in and watch Song Jiang offer fine clothes, delicious food, and precious gold and jade. After the knee-bowing ceremony, they presented sweet words and honeyed phrases. kind of world is this?

 3. Evil people may not necessarily receive evil retribution. This may be the profound intention of Mr. Shi Nai'an in creating character with the eyes of a wasp and the body of a snake! 

4. Gao Qiu's rise to fame was inspired by a note-taking book written Wang Mingqing, a Song Dynasty scholar, called "Hui Zhu Lu". It is said that Gao Qiu was a secretary for Su Dongpo and was good at calligraphy and writing. When Su Dongpo was transferred from the Hanlin Academy to another post, he recommended Gao Qiu to Wang Jinqing. "Little Su Xue Shi" in "Water Margin" is none other than Mr. Dongpo himself. In this case, Gao Qiu, the scound, was also a student of Su's school? Qin Shaoyou and Huang Luzhi must be ashamed to have such a fellow student. 

5. There is no that Liang Zhongshu was a corrupt official, and the "Shengchen Gang" is ironclad evidence. But even a famous general's son a loyal minister like Yang Zhi had to carry a load of gifts to the capital to find a way to bribe in order to get back on duty. In case, corruption seems to be the norm.
