Soon afterwards, Wang accompanied Mao Zedong to Lingxian county in southern Hunan province in aid of Zhu De. Jinggangshan had meanwhile been overrun by landlord militia and had to be reconquered. After Zhu De's soldiers joined the Jinggangshan base, they were merged with the existing forces to become the Fourth "Red Army". Yuan and Wang's 2nd Regiment was renamed the 32nd Regiment. Later in the year, Zhu De's 28th and 29th regiments crossed into Hunan. The 32nd Regiment was given the assignment of securing Maoping from the advance of the Kuomintang's Jiangxi units until his return.
