at the CDF after we had a discussion on this report

"Deino, thanks for the check. You are right on 71 being in CTC. I've corrected it below and merely reflected it as a brigade since I'm assuming all fighter units have converted to brigades. I haven't noted any operational difference between how regiments are operated vis brigades yet.
On 94, this was previously under Nanjing (ETC) but later merged with Jinan MR training base - per scramble, which technically puts it under CTC. However scramble lists it under NTC (not sure why). Location wise, I think it is unlikely to be under NTC control but borderline between CTC & ETC. Considering the depot status, I would provisionally put it under CTC instead.
Updated.
CTC: 20 (Tangshan), 21 (Yanqing), 53 (Wudangshan), 71 (Xishanbeixiang), 94 (Xuzhou) – depot
STC: 27 (Pulandian), 52 (Wuhan), 132 (Xiangyun)
ETC: 42 (Zhangshu)
NTC: 44 (Bikeqi), 88 (Dandong), 91 (Liuhe)
WTC: 1 Tng Bde (Jiuquan), 2 Tng Bde (Hami) – only training units left
Article:China to replace J-7 fighter jets with advanced models
I estimate J-7s may be withdrawn from combat service within the next 5 years and clearly won't go past this decade in frontline combat service."

So in summary, he comes to the same conclusion!
