According to the query of Baidu Library, the words commonly used by the ancients are often complementary explanations of names and mutual confirmation. Su Shi's ci really comes from "Looking for Poetry" (the battle of Zuo Zhuan's long spoon), while Su Zhe's ci comes from the traces of cars passing by. There is a saying in The Second Son of a Name that "Zi Zhan" and "Zhan" mean to look. Holding Che's family in a carriage is convenient to see. Zhan is related to history, so Su Shi's words are profound. The ancient meaning of "Ziyou" and "You" is the road, the road is rutted, and the road is related to reason, so the word Su Zhe is Ziyou. The relationship between sub-tour and sub-station is connected by "yes" and "zhe". As my dear friend said above, "yes" and "zhe" are both related to cars.
