Visit on November 7th

Hello, I will be in Xi'an on November 7th, a Tuesday. I would like to know if the bus tour will normally occur on this day, will all the attractions be open and functioning normally on this day? If an attraction is not open, will there be a replacement for another, or a discount on the price? Also I would like to know if in the visit to the terracotta warriors, there is possibility to buy some souvenir, since the tour there is Shopping Arrangement (in fact I would like to know if you have how to buy a miniature of terracotta warriors, do you know the price?) Thank you very much.
