Talk:602nd Aircraft Design Institute

602nd / 603rd
The only reference used for this page states at the top that its info is from wikipedia. Other articles here seem to reference the 603rd Aircraft Design Institute as the partner of Xi'an Aircraft Industrial Corporation. I seem to see some references to both floating out there, but it's unclear to me whether they are two separate entities or just a typo. Can anyone with better language skills than mine make a determination? Retswerb (talk) 23:04, 17 October 2020 (UTC)
