I'm wondering where to find a bao mu who can clean our house for a couple hours a week. What's the going rate these days?

I might be wrong but isn't a bao mu more like a babysitter? I think for a cleaning lady ayi is more fitting.

10 kuai an hour. Try Xiao Lu on 13529168284. She might be too busy though as she cleans numerous houses. If she offers her husband to do your house say no. He's worse than useless.

Baomu is what I've always heard people calling it. Ayi is just aunt, right?

I think your right godfear about it being called a baomu. Ayi is is aunt and that's what most people call their helper if they help take care of the kids. My kids call our helper Ayi. If I hear of anyone I'll post it on here.
