HONG KONG: After three decades of selling homemade buns on the streets of the Chinese city of Xian, 67-year-old Hu Dexi would have liked to slow down.
Instead, Hu and his older wife have moved to the edge of Beijing, where they wake at 4am every day to cook their packed lunch, then commute for more than an hour to a downtown shopping mall, where they each earn 4,000 yuan (US$552) monthly, working 13-hour shifts as cleaners.
Uh-oh! Daily quota reached.
