China is a nation of 5000-year history and civilization.Watching sports matches in a civilized manner is the representation of our culture and etiquette.Olympic Games is a window through which we introduce China to the world.Uncivilized conducts not only spoil the international image of China but also disturb the normal order of sports events.Sometimes such misconducts may hinder the performance of most athelets and prevents the healthy development of sports.(5) Therefore,let’s take immediate action so as to prepare for watching 2012 London Olympic Games in a civilized manner. Sincerely yours, Li Ming
