Introduction to the Red Army Dongchong Arsenal: In the spring and summer of 1930, the Hunan-Jiangxi Provincial Committee of the Communist Party of China sent people to You County to help establish the Soviet regime. In the autumn of 1930, the You County Workers', Peasants and Soldiers' Soviet Government was formally established in Caobo Chushui, and began to establish local armed forces. The Dongchong Arsenal was established in the ancestral hall of the original Cheng family at the foot of Sandou Ridge in Dongchong, and the surrounding hidden caves were used to open a repair workshop. The arsenal area retains the former site of the factory, the Red Army headquarters, trenches, drill fields, Red Army tombs, Red Army wells, Red Army caves, and Red Army slogans. The wells display weapons and manufacturing equipment such as guns, cannons, broadswords, and shuttlecocks at that time. Important attractions for red tourism.
