There have been lots of these "fansy" patches float around, but I find no such patches being wore by PLAN pilots. They all wear a shield shaped patch of PLAN aviation which is identical across all types of aicrafts on their right arm. Then some of them wear a round patch on their chest. They wear no patches on their left arms.
Besides, all these known official patches are incripted in Chinese characters or Pinyin, not English. What is the purpose of English anyway, to identify yourself when being a POW? So I have a very hard time to believe that these "fansy" patches are official PLAN items. They could be "personal" items by SAC working teams or just creation of internet cosplay items.
