Home-stay English tutor & take care of four years old boy

I'm a director of a cultural exchange organization in Shanghai, China. My husband and I have a four years old boy. We love music, movies, travelling and hosting people from all over the world.
We expect you to teach our son English as well as share some light housework. In exchange, we would love to treat you as a family member and show you around in the city. We will also offer you a separate room as well as three meals per day. Some allowance will also be offered.

In the picture is a guest we hosted from UK, she stayed with us for two weeks. We expect you to be courteous, friendly and adventurous and most importantly, love kids!
