A housekeeper who meets the requirements would get paid 12,000 yuan a month, but no one in his company is qualified for the job, Shi said.

Wang Xinshan, a professor at Wuhan University, said that as China becomes more open to the world, more foreign families in big cities such as Beijing and Shanghai have demands for high-end domestic services that are in short supply.

There is only one specialized vocational school in the country that trains professional domestic helpers, Wang said.

"More specialized institutions, and at higher education level, should be established to train more home service professionals," Wang said.
