Yes, TAM is short abbreviation of Tianamen.
Contrary to what some people might think the Su-27SKs China ordered were not meant for the RuAF, nor where they anything like refurbished from existing airframes.
The PLAAF made specific requests to strengthen the airframe and landing gear to increase the payload, and the Russians made changes on the frequency of the radar and ECM gear to not match their own.
There was plenty of talk that the radar was downgraded but it appears that the Russians were blowing their horn on the capabilities of the radar, and the radar just didn't live up to the marketing.
I do think that the Su-27 was better for China as a whole, but the PLAAF could have easily chosen the MiG-29 if it were not for political intervention because MiG was much more a known brand name than Sukhoi at that time. People often buy on the basis of reputation and branding rather than the more logical choice, and MiG was certainly much more famous than Sukhoi.
If it were not for that pivotal decision, maybe Shenyang and Chengdu might be manufacturing MiG-29s right now.
