The text on the logo says 超侧卫 which is the same the Weibo account name, which suggests it PS'ed. 超侧卫 also literally means "super flanker" which is very unlikely to be an official PLA motif.Interesting image of a J-11BS from the 55th Air Brigade (serial number 66560), which is remarkable in two ways; First, the Flanker carries a logo of some sort and second, behind the J-11BS there is a J-20 hidden.
This is especially interesting, since the 55th AB is rumoured to be under conversion to J-20s.
