thing we did the right thing to fight American in Korea, but the western world think Communist are absolutely devil based on what they did in 20th century... but at least, we change some oversea Chinese (US, HK, Taiwan) opinion in the US - let them understand some people from Mainland are smart, intelligent, some people from Shanghai, Guangzhou, ... are stylish - those are the only thing we can change so far. They can't believe that China become rich based on some rich people, or the modern buildings in some big cities.
