Why did Su Shi's father name him Su Shi?

This should be analyzed in combination with the names of Su Shi and Su Zhe. "Zuo Zhuan (Ten Years of Zhuang Gong)" has a cloud: "Look at it from the bottom, and look at it from the top." The original meaning of "Shi" in Su Shi's name refers to the crossbar set in front of the trunk for people to lean on. Shuowen explained: "Shi, the front of the car is also." The original meaning of "Zhe" in Su Zhe's name refers to the tracks of cars and the tracks of wheels running over. Su Xun knew the temperament of his two sons very well. In order to exhort and encourage his sons, he explained the profound meaning of naming his two sons in The Theory of Named Two Sons. He said: "The spokes are covered, and everyone has a job and a car, but Shi has nothing to do. Although, I didn't see it as a complete car when I went to Shi. Actually, I'm afraid of your lack of external decoration. The car in the world is nothing but a rut, but the person who makes the car's contribution is irrelevant. Although, the car servant died, but the suffering is not as good as the road. It's between the good and the bad. Well, I know it's free. " Su Xun's words mean that the wheels, spokes, hood and curb all have their own uses and are indispensable to a car, while Che Shi seems to have little effect and is dispensable, but if a car lacks Shi, it will not be a complete car. Because this crossbar was a little too ostentatious, Su Xun said "I'm afraid that you won't be dressed up" when he gave Su Shi this name, which reflected Su Xun's contradictory psychology at that time. He hoped that his son's personality could be brought into full play, but he was worried that he would be jealous because he was too ostentatious, so he gave Su Shi a word called "Zi Zhan", which meant that he should be cautious and cautious. For another son, Su Zhe, Su Xun wanted to feel more at ease, so he named it "Zhe" and the word "Zi You", which means to let him follow others. Although "Zhe" is not as eye-catching as "Shi", it is not easy to be hated. So we have to admire Su Laoquan's knowledge. I hope it helps you ~
