I have spoken to actual chinese people about their working hours. 996 is a thing. That is where you work 9-9 6 days a week. BUT they also made it clear that its entirely possible to make a living in china not doing 996, and the people who do 996 CHOOSE to do it because they make a ton of money.
I would think that is one of the main differences. While yes they have a similar culture its entirely possible to not work much and still have a good life in china. It usually isnt optional in capitalist nations with that same culture.
I have personally contemplated suicide due to how much i was working before, and let me tell you from experience if i would have had an option to simply keep my basic needs, food, and housing, yeah i dont even include clothes or healthcare idc id have been naked and well rested. That is what i would have done. But when you are stuck working constantly, exhausted, hurting, and just barely making ends meet, and know that if you stop you'll go hungry... that is what makes people want to end it all. The idea of death felt like a chance to rest. For it to all just stop.
In China if you are struggling there are places you can go that are run by the government that will help you. Even if your entirely unable to support yourself at all they will help you. If you see a homeless person and call the police in China they'll come (quickly) and check on them. They will offer the homeless person a ride to the nearest place to get help. The person can refuse if they want, but typically will go with them. They provide housing by either checking if you have a home already and helping you get to it, or by giving you a basic place to stay. They get you food. They provide job training if you are able to work, and help you find work and get on your feet.
Personally i have broken down sobbing before because i was sure I'd be on the street imminently, and probably freeze to death. In China it wouldn't have even been something i had to worry about.
I'll end my rant with this. I saw a post on xiaohongshu where an american asked "In China can you make a living by just working at a grocery store as a cashier?" the chinese response was "If you couldn't live comfortably doing that job why would anyone do it?"
