When I went there on the evening of April 27, I happened to encounter a large party program shooting. It was more amazing that when we walked in, the security guard did not stop us. When we walked to a very central location, we were told by the staff that the shooting was taking place here. Non-staff can't enter. The personnel on the scene were either staff with headset or actors in ancient costumes, and we felt like we had crossed, walked back, and exited when the door was stopped by a fence, wondering how we had just entered magically. The scenes performed by actors in ancient costumes are quite interesting and quite substituting.
