Great. The way the exhibits are displayed and the audience interacts very well. Exhibits are very rich. Wechat pays attention to the public number and enters the exhibit code. You can listen to the detailed explanation. After the special exhibition tickets are bought, there will be free guides, video combined with audio, not only the introduction of the exhibits themselves, but also expanded knowledge and video, and even interactive games, which are very good. Souvenirs have a good price performance ratio and are worth owning. All in all, it's great.
