From the angle of feng shui, the serious haze problem that hit our country can be explained in such a way i.e. the annual flying star that enters into the middle of the 2013 annual flying star chart is the worst star 5 yellow which is a EARTH element star. From 8 June 2013 to 7 July 2013 is 戊午 month which is YANG EARTH and YIN FIRE summer month. Thus the fire creates lots of earth (haze). There is lots of EARTH available.
