From what I can trace back to, here's the original transcript written in Traditional Chinese:
Translated into English would be:
Combining what Deino has stated and from what I can decipher on my own, the statement indicates the hope of the source author for the upcoming airshow to introduce the following:
1. Y-20B, i.e. Y-20s fitted with indigenous WS-20 turbofan engines;
2. Y-20BU, i.e. aerial tanker variant of the Y-20B;
3. Gyrfalcon, which is the nickname for the J-31/J-35;
4. WS-21 new turbofan engine(?) for the J-31/J-35;
5. Protoypes or first flight video footages of CH-7 stealth attack UCAV and other models by the Rainbow Company;
6. Stealthy ship-based/naval helicopters by AVIC;
7. Different kinds of stealthy missiles;
etc.
(Sidenote: What are WS-21 engines? Aren't the J-31/J-35 gonna be fitted with WS-19 engines?)
Speaking of which, just beneath Deino's tweet is the source author of the above information, which is this guy called 柳成梁 on Facebook:
Another Facebook post in a group called Modern Chinese Warplanes with the same content and translation as Deino's tweet:
I assume that this is where Deino sourced the above information from, or vice-versa.
By tracing the clipped photos in Deino's tweet, they are from the news report by CCTV-13 this morning (June 2nd, 2022 at around 8.51 a.m. local time):
(only available in Mandarin)
I looked back at the replay of CCTV-13's live news report this morning, specifically at the timestamp shown in those clipped photos. However, there was no specific mention by the CCTV-13's news reporters regarding any of the information above regarding alleged new planes, helicopters, drones and missiles for the Zhuhai Airshow 2022.
Therefore, there are 3 possibilities that I could deduce of regarding the above information regarding new planes, helicopters, drones and missiles for the Zhuhai Airshow 2022:
1. 柳成梁 has insider information about the 2022 airshow;
2. 柳成梁 has known associates being the insider of the 2022 airshow; or
3. They are just 柳成梁's personal wishlist.
IMHO, as long as we haven't yet reach Zhuhai Airshow 2022 and able to see those exhibitions with our own eyes, I would recommend taking them with a pinch of salt.
