Hong may have had a fight with a few passing heroes before and won only a few games. At this time, he was a little arrogant. At this time, Lin Chong is a modest and polite character. After all, he is still a prisoner. And Chai Jin knew Lin's skill, so he was very polite to Lin.

Hong is only a supporting role in Water Margin. In order to set off Lin Chong's superb martial arts, anyone who has read Water Margin will remember such a person. Because at that time, Yan described him vividly. Left a deep impression on the readers. Because it is to create a proud person like Hong, Hong's arrogant behavior makes the audience feel uncomfortable. Besides Hong Jiaotou's face, he also wants to set off Lin Chong's personality. Hong's arrogance on the wine table made Lin Chong an alcoholic, and he jumped up to compete with Lin Chong.

At this point, even if Lin Chong can stand it, Chai Jin and the audience can't stand it, and Hong's arrogance and arrogance make Chai Jin feel uncomfortable, not to mention the readers at this time. At this point, the audience and Chai Jin's psychological state is the same, just to watch the game between the two coaches and make Xiao Hongjiao make a fool of himself for the first time, so as not to realize that he is arrogant and doesn't know how much he has. At this time, Chai Jin and our readers' psychological state are exactly the same. Want to see Hong Jiaotou being slapped in the face.

This is the need of characterization. Generally, when shaping a role successfully or not, it is necessary to shape another unlovable role to set off the protagonist and show his aura.
