Beijing visit

Hi Guys, we are a family of four made up of a 4 year old, & 8 year old. We were living in Mozambique, then moved to South Africa. We coming to Beijing in July for a "look see" with the possibility of moving in December.

What International schools would you recommend? What is pollution like? Medical care? What would you ask to see?

I'd be really grateful if you could give us some guidance.
