This is just an anecdote but I have seen talks where the Chinese look at the silicon valley grind culture of long working hours and sacrifice and think how can these people be so lazy?

Working long hours isn't necessarily efficient.

Exactly. The OP didn't know any English teachers in China, or else they can verify that Chinese workers in private enterprises nap on the job/play on their phone/waste a ton of time, to get through the long working hours.

Interestingly I’ve heard this observation about American managers in US multinational businesses in Europe, that they seem to performatively do the long hours, for the sake of their own managers view of them, but that little of it is actual productive time.

I’ve not really observed it myself, and I’d suspect that part of it might be very different styles or ways of working. But maybe there’s a grain of truth there.

The output in relation to competitors is what matters in the end. At this point their results are impressive.
