An Special case
Look at the city of Anqing (30.5319° N, 117.1151° E), its PM2.5 and O3 concentration has a strange phenomenon. I clipped some figure of its air quality status (2016-01-04 local 12:00:00)
Fig 1 Anqing City and Chizhou City These two nearby cities are in the distance less than 60 Km, has the similar PM2.5 conc with different O3 conc
Fig 2 Anqing City and its surrounding area 
What attract me is the high conc O3 of Anqing City comparing with its nearby area. And I found this feature is rare in China.
Anyone has some theory to explain that? Any discussion or advises would be great!
