When Wu Jue was young, he was resolute and ambitious, good at riding and shooting, and could read to understand righteousness, and when he was a minor, he joined the Jingyuan Army (now Gansu) with a good family. During the reign of Huizong of the Northern Song Dynasty, the Western Xia soldiers committed the Song realm, and Wu Yu followed the army to ask for it, and made up for the righteous lieutenant with meritorious service in battle, and was later promoted to a team general. In the last years of Huizong, he went to Jiangnan with the army and rebelled. In the early years of Qinzong Jingkang, the Western Xia soldiers committed the Song Huaide army (now Ningxia Tongxinnan), Wu Jue followed the army to fight again, the Xia army was defeated, Wu Jue led more than 100 cavalry to pursue, beheaded the enemy more than 100 levels, and then was promoted to the second general of Jingyuan because of his merits.
In the second year of Gaozong Jianyan (1128), the Jin army crossed the Yellow River, went out of Daqing Pass, and sought to capture Jingyuan. At that time, the Song Dynasty was under the control of the Jingyuan capital. Qu Duan ordered Wu Jue to march into the army to occupy Qingxi Ridge, go around the enemy's back, and then return to counterattack the Jin soldiers. Wu Jue led his troops to base on Qingxi Ridge, defeated the Jin soldiers, and pursued the enemy for more than 30 miles. Since then, Jin Bing has always been afraid and did not dare to invade Jingyuan easily. In the third year of Jianyan, Wu Jue was promoted to Zhongzhou (now Zhongxian County, Sichuan) because of the thief Kou Shibin.
In the spring of the fourth year of Jianyan (1130), Wu Jue was promoted to the deputy head of the Jingyuan Road Mabu Army, and was still subordinate to Quduan. In this year, Jin Shuai Lou Su and evacuated the Jin soldiers to Guannan. Quduan sent Wu Jue to resist the enemy in Pengyuandian. In the first battle, the Jin soldiers were defeated. The Houjin people found out that Wu Jue had few soldiers, so they reorganized the army and fought again with Wu Jue. The Jin soldiers came with heavy troops, but the commander of the Song army, Qu Duan, sat back and did not help, Wu Jue was lonely and difficult to support, so he was defeated, and Qu Duan also returned to Jingyuan. After the Song army returned to the army, Qu Duan claimed that Wu Jue had violated military discipline and was defeated by not listening to moderation, so he dismissed Wu Jue from his post as deputy chief of the military and demoted him to Doctor Wuxian. Sichuan and Shaanxi Xuanfu disposed of Zhang Jun to cherish Wu Jue's talent, and soon reinstated Wu Jue as the deputy governor of Qinfeng Road, and also governed Fengxiang Mansion (now Fengxiang, Shaanxi).
Fengxiang Mansion is a place where the two armies must fight, because of the frequent wars, so the people are not happy. Wu Jue took effective measures to compensate the people, settle the people's livelihood, and the people relied on peace.
