In the first grade class of American elementary schools, this scene may be staged: when the teacher asks, "What is 7+8?" China children can immediately answer "15" without thinking. What a genius! American children may not have enough fingers, but they should take off their shoes and use their hands and feet. They are so stupid! American students are notorious for their poor math skills. It seems that China's education cultivates "math prodigies"; American education, on the other hand, trains "mathematical idiots". However, where did those "Chinese prodigies" go when they grew up? Throughout the history of modern world science, western education, especially American education, has trained a large number of top scientists. Here is a question, is learning for grades or for application and innovation? Of course, the second generation of Chinese in North China today, although somewhat influenced by American traditional educational ideas, is no less than the United States, with engineers, postdocs and professionals everywhere.
