I'll be spending a week in Shenzhen visiting my son and his girlfriend. They will be working Monday - Friday, but I will probably have lunch with them, as they have a long lunch break. Just looking for ideas of things to do on my own in the afternoon. Spa? Shopping? Sightseeing? Is there any sort of group tour in English that I could join? I'm usually happy with just walking and exploring. Staying in Futian district. Looking on the map, it looks like it is near the Science Museum. (I don't know if that is a good landmark).
