Significance introduction: The old site of the main hall is not only the front line for the distribution and sales of the central government newspapers "Xinhua Daily" and the weekly "People", but also an important place for the Southern Bureau and the leaders of the Communist Party of China to carry out united front work in the capital. The "Xinhua Daily" sales department has been fighting here for 6 years, and has published dozens of progressive books and periodicals of various types, making great contributions to the United Front public opinion propaganda cause of the Chinese Communist Party's Anti-Japanese War and the early stage of the Liberation War.
