I have following questions,
1. Is above a realistic plan? My wife and kids will be traveling with
me. They all are healthy and athletic.
2. Would you recommend staying an extra day in any specific location?
3. I have some distant friends in Shanghai, I am hoping they will be
give some sound suggestions on local travel in Shanghai.
4. Do railway stations have good showers? Any suggestions on where I
can find good showers?
5. Things to carry.

Thanks,
Tiiger
