J-10Cs had 2XX production serials when they were flying in primer, like so.J-10C in the upcoming movie Sky Hunter. Not sure if this is real or not, but the production serial is on the pilot's seat: J10C0213. Batch 2, unit 13?
(2048 x 756)
CAC probably views the J-10C first batch as a continuation of the J-10B/C production run.
Thus, 0213 is simply the 13th example of the first J-10C batch that we already know about.
