In his Red Star Over China, Edgar Snow mentions visiting the small towns of Yuwang Bao and Yuwang (予旺, 36°49′N 100°23′E / 36.817°N 100.383°E) located in today's Tongxin County. At the moment (summer/fall 1936), Yuwang Bao was the location of the headquarters of the First Front Red Army, where Edgar Snow met with the army's commander, Peng Dehuai there. Edgar Snow described Yuwang Bao as follows:
On the high, stout walls of Yu Wang Pao a squad of Red buglers was practicing, and from a corner of this fortlike city flew a big scarlet flag, its yellow hammer and ciskle cracking out in the breeze... We could look down on one side to a clean courtyard, where Muslim women were hulling rice and baking. Washing hung from a line on another side. In a distant square some Red soldiers were practicing wall scaling, broad jumping, and grenade throwing.
