Introduction to the reception room: After the "Southern Anhui Controversy", due to the intensification of the Kuomintang's white terror, in order to facilitate meetings and talks with progressive people from all walks of life in the capital, Zhou Enlai, Dong Biwu and other Southern Bureau leaders often met in the reception room on the second floor of the sales department. Relevant people in the Kuomintang-controlled areas and heads of various democratic parties held secret meetings and talks. The picture shows the reception room at the old site of the main building.
