The Second Division of the New Fourth Army abandoned its station and moved to Daliangying. Acting commander Chen Yi, acting lower committee Rao Shushi and chief of staff Lai Chuanzhu also arrived in the north. Zhang, the deputy commander, arrived early. At this time, it became the anti-Japanese command center in Central China. Huanghuatang was originally named Huanghuatang, also known as Dusk Pond. During the large-scale production movement, local soldiers and civilians dug deep into the pond to increase the water storage capacity, and Zhang and others proposed to change their names. The thatched cottage where Zhang lived is still there. During his stay in Huanghuatang, the headquarters of the New Fourth Army was code-named "Yellow River Brigade".
