Am back. Thanks to all for the tips.
I too enjoyed the temple of Heaven and in fact the park that is part of the area. Interesting to see Chinese couples practicing ball room dancing.
Basically , used my 70-200 with a 2x extender for at least 60% of the trip including the Warriors at Xi' an. I ignored the figures in the glass cases as I didn't have a polarizer with me and the crowds made it a lost cause. There is always a good use for postcards someplace along the way.
