If that's how you feel, show me the working WS-15/WS-18/WS-20 engine in mass production. Show me the completed CPU fabricated by 5nm process in commercial use. Then come back and talk. Until then all you have is a bunch of hot air on a message board. The American President Theodore Roosevelt has a famous saying, "Speak softly and carry a big stick." Unfortunately some well meaning Chinese nationalists seem to do the opposite.
The US landed on the moon in 1969. Where is China? If all goes well, the same mission in... 2035. 66 years behind. In some areas China is lagging as badly as the Qing dynasty.
If you have no results then you got nothing to talk about.
This is the most stupid post I ever see US is developed economy with $40,000/gdp percapita China is developing country with $10000 gdp percapita Of course there is different priority
China defense budget is only 1/5 of US defense budget US has constant war in the last 40 years China didn't have any .
And you of course cherry pick the field where US has a lead But China too has lead over US when it come to missile, NEV like battery technology, Green energy, Transportation etc
Now come back to the gas turbine US has more than 40 years lead when it come to GT US was present at the birth of GT technology. China was hungry and destitute at that time with most of the country destroyed due to unending war So of course US lead But China did catch up in GT after WS 10 as one of the few countries that can produce Turbofan engine with T/W ratio of 8 And she is working om turbofan enginw with T/w ratio of 10 as it now only US has production ready Turbofan with that ration Russia is still experimenting So it is not so bad for latecomer.
US has a trhirving air transport industries for the last 80 years China didn't start having civilian airline until 1980's. It take enormous amount of money and time to develop Turbofan engine Here it is P&W take 30 years and 10 billion of dollars to develop the engine
Now about Moon landing US practically moved and transplant all of the german engineer with the operation paper clip. Together with huge NASA budget make possible to land man on the moon in 60's China didn't have that kind of money and also landing man on the moon is not priority
If I have to say it is complete waste spending that kind of money to bring rock from moon The same job can be done more efficiently by using robot and that is exactly what China did this december
I am not saying space technology is not important but it is not priority when half of Chinese population still live on $200 per month
