That is because most the Chinese are hard working and do not work on a 7 day work week. Most Chinese get X days off per month or X days per 10 days if more than 3 days off per month. Not X days per week.

I believe most Ayis get 1 day off per month. Factory workers 1 day off per 10 days. Office workers 1 day off per week.

Actually, with the bigger factories their workers are getting 1 day off per week (e.g. established textile factories, foxconn, etc.).
