Thanks for your concern in your letter about the smog which frequent strikes some areas of China. I’m also very worrying about such a terrible weather. It has brought much inconvenience or rather harm to people's health such as road accident, bad coughs and even lung cancers and so on.

It is known to all, good environment comes from careful protection. But we should do what we can protect it. I believe a small step can make a different. Try to drive less and choose air-friendly products. Only when everyone had the environmental awareness can we have a blue sky. Hope to hear from you and share my good ideas.
