IF I fly in to Shanghai and obtain a 72 hour free transit. Can I travel to Zi'an province?

I read "Passengers transiting in Shanghai, Zhejiang, or Jiangsu can move around the three places". I will have a 49 hour layover in Shanghai. Am I allowed to leave the area to go to Zi'an province to see Terracotta Warriors? I fly in to Shanghai and back out of Shanghai.

Also we have a 12 hour layover in Kunming. Can I apply for the visa in both locations? Just wondering if there is a way to get out of the airport in Kunming as well?
Thanks
