Guys ... I think are mixing up a few things: First of all there are two aircraft shown ... 2-39 is simply a twin-seater (original model) from the second block ... whereas all aircraft (not shown) 101-104 are from the first serial block J-10B.
The single aircraft 201 is so far something of a mystery and reportedly said to be a prototype for the J-10C.
So simple...

Why this one has a such strange camo?
