3744 hours. Dayum!

Just going off basic numbers:

- 3744/52/5 = 14.4 hour day if they work 5 days a week

- 3744/52/6 = 12 hrs if they work 6 days a week

- 3744/52/7 = 10.3 hrs if they work 7 days a week.

That is, indeed, what 9-9-6 means: 9am-9pm (12hrs) * 6 days per week.

9-9-6 is also not full productivity for 9-9-6.

Office workers will eat lunch, take a 1-2hr nap in the afternoon, and also eat dinner with their coworkers within the common 9-9-6 rhythm. It still takes a significant chunk of time, but the actual working time butt-in-chair is closer to 54 hours

You lose productivity doing 996 anyways so how can you maximize past that?

> Urban workers in China do 3,744 hours per year

For reference, that's 10:15 per day, 365 days a year. Or 996 without vacations, if you intend to have one day off.

996 has never been a standard work duration for urban workers in China, aside from some tech companies that promoted performative work ethics. And even there, people do take vacations.
