Introduction to the address of the instructors of the Central Red Army: In December 1934, the Central Red Army passed through Liping during the Long March. The headquarters of the instructors was located in the residence and business of the wealthy businessman Zhang's family on Qiaojie. The Central Red Army Instructor, also known as the Central Revolutionary Military Commission Instructor, was established on August 26, 1934, with division commander Zhang Jingwu, political commissar He Changgong, chief of staff Sun Yi, and director of the Political Department Li Xi. In December 1934, the instructors of the Central Red Army entered Liping, leaving only the division headquarters and some personnel. During their stay in Liping, He Changgong and others made significant contributions to the selection of the residences of central leaders, the selection of the location of the Liping Conference and the smooth convening of the Liping Conference.
