It tells the story of the early years of Tongzhi in the Qing Dynasty, when corruption was rampant. Shaanxi was in a hurry, and the capital moved to suppress it. Nianxi attacked Shaanxi with 200,000 troops in three directions. Fortunately, General Duolonga led his troops to suppress the enemy, and defeated the Nian thieves at Jingzi Pass, and the Nian thieves escaped. However, there are still beetles everywhere, and Xiaoxiao is rampant, especially where the two provinces of Shaanxi and Henan meet the border, where the defense is the most tight. Tongguan, Wuguan, Jingziguan and other places are on the border with Henan. I am afraid that Nian bandits will come from Quexiang, Lushi and Jiaoer Mountain in Henan, so all the passes are heavily garrisoned. However, in the southern part of Huayin County and the Shangnan area, there are still many partisans lurking, causing disturbances from time to time. The residents are frightened overnight and cannot sleep peacefully. The Qing court appointed General Duolong'a as the Imperial Envoy to supervise Shaanxi's military affairs. Duolong'a then took charge of Shaanxi and dispatched powerful troops from all over the country to station at various passes to suppress and investigate, sparing no effort.
