Do you have an estimate how many J-20 are in PLAAF by now?
 
Can anyone explain what's up with this post? It seems not to show anything special ... "钓鱼佬之中原雄鹰" = "The Central Plains Eagle in the Fisherman", what's the meaning??

I roughly know what he meant. I am pretty sure it has nothing to do with the J-20 fighter. So, you don't have to pay attention to this Chinese text.

钓鱼佬: A Chinese nickname for people who like fishing very much. They like fishing very much and regard it as the greatest joy in life. But they are different from fishermen (fishermen fish as a profession, while they fish for fun).

中原雄鹰: The Chinese nickname for a brigade-level PLAAF unit stationed in Henan. (PLAAF 56th Aviation Brigade)

So, the meaning of this Chinese text is:
The J-20 of a PLAAF Henan Brigade was photographed by a person who likes fishing.

There is a river next to the air base. Many people fish in the river. They often take pictures of fighter jets.

@Deino The PLAAF's brigade-level aviation combat units. If they perform very well, they will be awarded exclusive Chinese titles by the Central Military Commission. You can find the correspondence between these Chinese titles and unit numbers in the relevant items on Wikipedia (Chinese version).

It one of the best agile fighter jet similar to EF-2000/Rafale but still lag behind the TVC equipped F-22, TVC equipped jets are more agile then Canard equipped jets

wasn't their talk about J-20 getting TVC in future or am I mixing up things?

maybe not anymore, they are just gonna inducting the WS-15 version.

WS-15 has enetered mass production or is it in limited production for testing? Hopefully it's the former.

IMO. Future versions of the J-20 (updated versions after the WS-15) may not necessarily adopt TVC nozzles.

We all know that TVC nozzle technology is to exchange power for maneuverability. That is, it sacrifices propulsion power (2%~10%) in exchange for high maneuverability. The J-20 canard solution is another technical route to obtain high maneuverability.
Since these technologies are highly military secrets, it is difficult for us to objectively evaluate the pros and cons of these two technical routes. But I think it is unlikely that we will see two technical routes with the same purpose appear on the same fighter. On the contrary, I think we may see the TVC version of the J-35 first in the future. (The TVC version of WS-19 is currently being tested.)

Since the J-20 has a huge fuselage and already has high maneuverability, I think its future development direction should be to further enhance its informationization capabilities.
It itself has the ability to become a front-line air command post (closer to the front line than AEW&C). Therefore, its more surplus power should be converted into electricity to provide power support for more information equipment, rather than in exchange for repeated high maneuverability brought by TVC.

Personal opinion, for reference only!

Not sure yet, we have seen J20S flying with WS-15, and we have heard rumor the J20S is entering product this year, so far, it's all we know.

agreed, the airforce probably don't wanna exchange that dead weight for tvc.

The PLAAF may not even want to exchange range for speed, there could be two version of J-20 in production in the future, even with the maturity of WS-15, since J-20 equiped with WS-10B/C will be most likely has higher range than these with WS-15, thanks to the much higher bypass ratio of WS-10.
