Well it is hard to say what his intention is. Everyone has different interpretation. In my opinion what he said is loud and clear. He expects J-20 to retire around 2035, only less than 2 decades from now. J-20 is only the leading model of a family. 2035 retirement is only feasible if the next gen jet is fully operational and has enough quantities. So he hinted both the progress of the next jet, as well as a rough timeline. Personally I expect a 2025 first flight of the next/next gen jet (either 5++ or 6) from CAC.
A rough translation:
- Title: to J-20 in 2035
- When you were born, you were the splash of CAC. We (the designers) were happy. They (the fans, observers) were dubious. (this paragraph is referring to 2010/2011 time frame)
- When you grow up, you were the highlight of Zhuhai. We were proud. They (the fans, observers) were excited. (this paragraph is referring to the 2016 Zhuhai debut)
- Later, you were the defender of China's air space and sea. We felt responsibility. They (the other parties, i.e. the enemy) felt deterrence. (this should be 2017 - 2035)
- Now, you are the legend of Eagle family. You were the lead role. They (everybody on our side, not including the enemy) are hopeful.
