I don't know. Probably not. But this photo still contains useful info since it is taken recently. Not all of the Wuhu J-20s are rehearsing for the July 1st flyover this year since we see 15 of them rehearsing in Tianjin right now. This makes sense since sending all of them to Tianjin will leave the Eastern seaboard undefeated.
My hypothesis for J-20s participating in the parade:
1) 5 from Dingxin
2) 5 from Wuhu
3) 5 from Cangzhou
Good and reasonable theory! ... and now please add 5 more from Anshan!
