China also has 7 main federally recognized holidays. Although, one interesting thing they do is "weekend shifting" where they move the official work days near, e.g. the Spring Festival so that people get a full week of holiday (at the cost of a longer workweek or a one-day weekend right before/after it): https://en.wikipedia.org/wiki/Public_holidays_in_China#Weeke...

The 666 workweek(6 days a week 6 am till 6pm) is definitely real in some companies and it's a big problem with work culture especially in tech. But in general I'm sure they do holidays.
