Yangjialing Revolutionary Site is divided into two parts, the south part and the north part along the road. The south side of the road is the central auditorium of the year. The north side of the road is the former residence of Mao Zedong, Zhu De, Zhou Enlai, Liu Shaoqi, and other central government leaders. The 7th National Congress of the Communist Party of China, which is of historical significance, was held in the central auditorium. At the meeting, Mao Zedong Thought was determined as the Party's guiding ideology. In 1946, Mao Zedong met with the American journalist Anna Louise Strong here and proposed the famous theory that "All the reactionaries are paper tigers."
