I had a look on Google Earth at the Zhenhai Expo Park and noted that there were a few images linked in Panoramio. I think what the AH-64 Apache trailer images show is the view from an entrance to the Expo Park showing the front of the building with the wooded mountain/hillside in the background? There is also an historical building on the right with the walls visible in the trailer images. It appears that the images were taken when the replica AH-64 Apache was delivered to the Expo Park.
