While this is true, the way of life and rule in China did in fact change with the introduction of communist rule after WWII.
As an actual country and people in general they are still largely the same. The way said rule is being implemented and enforced both legally and socially now is the difference which is transforming them as a whole into something other than they were before, which is an ongoing process to this day by design of the ruling party/government.
They didn't change deeply. The emperor became the Party. And "law" is just becoming official, that's all ; before you just got executed, murdered or killed. Like any country in the world. Remember a guy named Lincoln ? Good ideas, but not for some guys.
China's rules are just more drastic than ours. It's like the "one child law", which not really a law but a financial burden from the Party to enforce you to have only one child, which got many newly born girls killed discreetly (or so).
I'm not defending China way of ruling. I've worked and nearly lived with Chinese people, and I saw and comprehend what is happening.
Some follow the rules and live their lives as is, blindly ; but some make choices of their own, and when they want to undo it or get in touch with other chinese (they are living in groups, like a small China Town, even in France), they get rejected from their own (it's the only country to do that, over nearly 30 "big" country I've seen in my life).
My only point is : we have no fucking clue of how to make a country of 1 billion dudes not killing the planet and still holding up to the world and themselves. No one on this planet does. So don't judge like a kid (not directed to you, it's a statement and it's also work for me) something you can't even start to comprehend.
This is also true - China didn't survive as "China" all those years by being friendly to just anyone but to be fair, Japan isn't exactly innocent either.
Indeed. China survived because they were attacked from everywhere, and in order to survive as an Empire, they had to follow a leadership, like all of us. Even if it's not fair nor legit. It was, and still is, war. Just a different one.
And japanese invaded China a lot of times (WWII last time), and they are still fighting over some islands today. It's true ; so many war between them that they hate each other like Chileans and Argentinians (don't put 2 of them in a closed room or one will die).
