Not a good week to visit China!
Everyone that works takes their annual vacation at the same time with their families, and the Roads are bumper to bumper traffic!
And so is the SMOG!
It is still warm to hot & humid until after Oct 10 or so.

The tourist sites are just as crowded with families & their small children.
Long waiting lines.
Hotels are crowded and Breakfast dining rooms are full.
Flights will be full, as well.

Oct 8 was the only day the clear BLUE sky was visible after most vacationers have gotten home from their travels.
If I were to go back again, I would plan on arriving about Oct 10!
