Introduction to the former site of the headquarters of Liu and Deng's armies: In mid-June 1947, Liu and Deng's armies left the Shangdang area in southeastern Shanxi and entered northern Henan. The headquarters was located in Ma's Manor. Commander Liu Bocheng and political commissar Deng Xiaoping stayed in the east and west wing rooms of the third entrance hall on West Road in Zhong District respectively. The "Southwestern Shandong Operation Conference" on June 22 was held in the main room of this hospital.
