As far as I know, there are 6 permanent exhibition halls, and the rest are mobile exhibition halls (?).
4F houses the Duan Chenggui Calligraphy Museum, exhibiting replicas of Su Shi's "Ode to the Spring Scenery of Dongting Lake and Ode to the Pine Wine of Zhongshan."
3F contains the Jilin Provincial Modern History Museum, covering topics from the resistance against Tsarist Russia to the Xinhai Revolution, from the anti-Fengtian uprising to the War of Resistance against Japan and the liberation. A detailed look will inspire respect for these figures.
2F is dedicated to the ancient history of Jilin Province, from the dawn of civilization to the elegance of the Han and Tang dynasties, from the grandeur of Songmo to the splendor of the Ming and Qing dynasties. It covers the people of Yushu and Antu, the Buyeo Kingdom and Goguryeo, and the Liao, Jin, Yuan, Ming, and Qing dynasties.
The only drawback is that many artifacts in the Han and Tang Dynasty exhibition hall are on loan, resulting in a less than ideal experience. History buffs should definitely not miss it.
