We have 6 au pairs in training. Most of them are from outside of Zhengzhou and can't afford housing. We really didn't have the funding for another house, so we bought these dorm bunk beds for 350 yuan each (we bought 3 sets) and put them in two different homes. Most of the au pairs sleep at our Big Kid House and work at the other homes during the morning or afternoon. Some of them attend English classes when they aren't working.
They expect to go stateside in approximately four months, then we will train some more. It appears whoever is sleeping on the top needs to make their bed.
