Watching football in China is very different from watching football in the United States. China people are spectators. Many people like to be lively, but they don't participate. A non-participating audience naturally likes the scene more, the better. Therefore, many domestic fans don't want strong teams to lose. Americans watch football in different ways and always like the weak team to win.
As an education, the most important function of physical education is not to motivate people to win, but to treat failure and respect opponents.
A freely competitive market economy needs active people, not bystanders. In a highly competitive society, sports is the best way to shape a dynamic person. Unfortunately, our sports authorities and the public lack sufficient understanding of the educational function of sports.
