Introduction to the New Fourth Army’s Third Column Headquarters: The former site of the New Fourth Army’s Third Column Headquarters was Yan Fuxing Building, which was a residential building in the Qing Dynasty. In October 1940, Su Yu and Tao Yong commanded their soldiers here to hold on to Huangqiao, repelling seven charges from the Kuomintang die-hards, and made immortal contributions to the overall victory of the Battle of Huangqiao.
