Circle of Friends of WeChat was refreshed continuously with “blue sky” photos yesterday. Green mountains, clear water, blue sky and verdant plants all indicate a typical fine summer day. From January to June in 2015, Hangzhou enjoyed 111 days of good air quality and suffered 70 polluted days reach. The days of good air quality on year-on-year basis increase 6, excellent rate is 61.3%, and grows 0.3% on year-on-year basis.

    The so called “West Lake Blue” reflects a determination to manage Hangzhou’s environment well.
