Introduction to the former site of the Sibao Linjiang Campaign Headquarters: The former site of the campaign headquarters is Chen Yun’s former residence. In 1947, Comrades Chen Yun, Xiao Jinguang and Xiao Hua led the South Manchu army and civilians in a bloody battle, repelling four enemy attacks in 108 days. Finally, on April 3, we won the final victory in the "Four Guarantees of Linjiang Battle". This victory not only reversed the situation in the Northeast and changed the enemy's advance and retreat, but also brought about a strategic turning point on the Northeast battlefield, laying a solid foundation for our army's subsequent comprehensive counterattack and Liaoshen Campaign.
