The original meaning of the word "Zhe" in Su Zhe's name refers to the traces of cars running over and wheels running over. There is a saying in Zuo Zhuan's Ten Years of Zhuanggong that says, "Go down and look at it (look down and go back)". Su Zhe's word "Ziyou" means to imitate and follow. To put it bluntly, follow others. Su Zhe is much more reserved than his brother Su Shi in treating people and things.

On Su Shi and Su Zhe
The theory of two names is the reason why Su Xun, a poet in Song Dynasty, wrote the names of his two sons, Su Shi and Su Zhe, expressing his hope and warning to his sons, and introducing their personalities and names.
Wheels, spokes, covers and wheels all have jobs related to automobiles, but Shi alone does nothing. Although, I didn't see it as a complete car when I went to Stone. I'm afraid you're just a poet. Cars in the world are just ruts, and it doesn't matter who contributes to them. Although the valet is dead, suffering is not as good as the road, it is the road, and good lies between good and evil. I know it's free.
Wheels, spokes, railings around the roof and carriage all have their duties in the car, but railings seem to be useless as handrails. Even so, if the crossbar is removed, then I can't see that this is a complete car. Poetry, I'm afraid you won't hide your edge.
There is no car that doesn't follow the rules in the world, but when it comes to the credit of the car, the wheel tread has never been involved. Even so, the car crashed and the horse died, and the wheel marks were hard to blame. This wheel seal can be between good luck and bad luck. I know you can reassure me.
Creation background
In the sixth year of Li Qing (1046), Su Xun went to Beijing to take the exam. Although Su Xun's intellect can be a "teacher of emperors", it still falls behind in the corrupt imperial court and dark officialdom. As a result, he lost confidence in the imperial examination and the imperial court, and instead pinned his hopes on his two sons. After returning to China the following year, Su Xun wrote a profound Theory of Two Names. Su Shi was eleven and Su Zhe was eight.
Ten years later, Su Xun sent his two sons to Beijing to take the exam. After seeing Zhang off in Chengdu, he listed six questions to test the two brothers, while he peeped through the wall. After they get the question, they think separately. In case of doubt, it refers to asking stone and stone to knock several cases upside down, which means "managing the note"
Also refers to the second question, Su Shi tick the second question, because there is no source, began to answer. After the exam, Zhang said to Su Xun: "The second sons are all geniuses, and the elders are smart and lovely, but what a few people value is that what they have achieved is still alive."
