I visited the main museum three years ago. Actually, the contents of the Qin and Han Dynasty Hall are all in this museum, so if you have been to the main museum, you don't need to go back to the Qin and Han Dynasty Hall. The guide Feifei's explanation was very good, but she only talked about the two main halls, the City and Mausoleum, and the Skills and Beauty. She didn't take the tour. She only talked about two additional cultural relics, which was a bit disappointing. Everything else was perfect.
