SK is doing fine, very fine indeed, in a lot of aspects not just in material sense like tech/business, but in cultural as well. Don't get me wrong bro, China is doing fine under the current politico-socio structure in developing the hard powers, creating material wealth, look GDP is growing fast, people are getting wealthy, etc. But, is China doing well in social aspects? Just look closer, look deeper, into the culturally-close East Asian countries like SK, like JP, TW, definitely you will notice some difference in social behaviour between China and them. I travel to Seoul frequently, hangout with SK guys a lot in Shanghai, can speak a little of their language, I find a lot of lost Chinese merits well preserved by them. They don't talk patriotism, they do it. They have less family rituals, but they are real family-centric. And others, all we need is just open our heart to see bro ...
So I would say SK has learned a lot from ancient China. Maybe something to learn from nowadays China, but socialist model ... China can keep this treasure it to herself, it's China's proprietary weapon to success, no one allowed to take it ...
