Training programs aim to improve quality of service and raise living standards

Wu Qingchun, who has worked as a live-in caregiver in Shanghai since 2014, earns 5,500 yuan ($812) a month.

The 43-year-old native of an isolated village in the southwestern province of Guizhou appreciates the job because her wages help to support her family back home, where her husband looks after their children ages 18, 16 and 14.

"What I earn in a month here is equivalent to what an average family can earn in a year in my hometown," Wu said.
