Chu people who seek swords by boat and Zheng people who buy shoes are all those who stick to the rules. Yes, some parents in life are using past experience to educate their children now. They feel that as long as they learn mathematics and physics well, they are not afraid to travel all over the world, but they don't know the importance of literature. Just like Chu people and Zheng people, they will not adapt to the changes of modern society.
