Chai Jin, a native of Henghai County, Cangzhou, is known as the Chief Officer Chai because he is proficient in martial arts and loves to know who is a hero. He is also known as the river's lake whirlwind. In Water Margin, Liangshan started to grow from Lin Chong, but it was Chai Jin who "fooled" Lin Chong into Shui Bo. Taking "Little Whirlwind" as Chai Jin's nickname is a mockery of Chai Jin, which is pure "bad words".
Some researchers also believe that "whirlwind" is a vortex wind formed by the intersection of two winds in opposite directions, and the wind speed is very fast, which can roll up sand. In superstitious legends, cyclones are considered as "ghosts". "Little whirlwind" means Chai helps Jin Jin who wants him.
Chai Jin's personality characteristics and the significance of forcing him to rebel.
Chai Jin, a small whirlwind, is clever, very loyal to Liangshan's cause, and good at improvising. There are not many descriptions of Chai Jin in Water Margin, so Chai Jin's personality is not very prominent. Generally speaking, he is proficient in martial arts, hospitable, helpful, makes friends with heroes all over the world, shows no consideration for human feelings and lacks leadership style.
Chai Jin was exterminated, which deepened the theme of extermination, because Chai Jin was the eldest grandson and had "hard evidence" at home. Especially in the feudal society with strict hierarchical concept, Chai Jin naturally belongs to the upper class. Although he sympathized with and supported the heroes in the Jianghu, he never had the idea and understanding of rebellion. Only to be bullied and killed by Gao Lian, the magistrate of Cangzhou.
As a result, Chai Jin, a small whirlwind, was caught up with Liangshan by the feudal ruling class, which naturally deepened his thought of retiring from Liangshan, which was of special significance.
