Just normal to see the U.S. athletes to wear masks

 U.S. athletes came, the plane at Beijing airport just put a mask on. How should we view these events?
I do not think the foreign part of the athletes to wear masks in China, and even the opening ceremony of the Olympic Games wearing masks, are What an arrogant contempt for us, and even so would like to achieve in politics what purpose, only shows that they have neither knowledge is rude.
should first be made clear is that I think most of the foreign athletes to wear a mask health, self-protective behaviors, they had prepared with masks to China shows that they wear masks not just in China, in their own countries and other countries also need to wear. because they bring the environmental masks in order not to Beijing Olympics and the temporary development, and certainly before, and even their countries also need to regularly wear a mask when. In other words, environmental protection, air quality in the quality problem is a global problem, is by no means unique to China problem. Therefore, they wear masks to understand and sympathize with us, we must also sense the seriousness of environmental problems and urgency. Who we are living in the same planet do?
We also acknowledge the past, Beijing air quality does exist room for improvement, but Beijing has taken a series of environmental measures, the recent test data show that Beijing's air quality has indeed been greatly improved, the basic environmental requirements to the Olympic Games, in particular, near the opening of the Olympics these days, the air quality will become better and better. You can not believe that our verbal commitment, but you have to believe in science, I believe that data, which is the most basic knowledge of science. If in such circumstances also wear a mask, only shows that they prejudiced, the lack of scientific knowledge.
come at the end of the foreign athletes to wear masks, but also a rude behavior. As to the others to dinner will not be able to own , to the people still wear a mask, not eating, not drinking did not dare to sit, and the owner did not even shake hands, and this is a very rude behavior. Of course, as the owner for such rude people who do not have to flies into a rage, his rude manner that we can not do without. We try to improve
peace of mind to look at the U.S. athletes to wear masks.
