the late 1130s. The mutiny would cause Emperor Gaozong to move his capital to Jiankang. In 1130, Wuzhu, a Jurchen general, crossed the Yangtze southwest of Jiankang and then captured the city. Wuzhu set out from Jiankang and advanced rapidly to try to capture Gaozong. The Jin seized Hangzhou on January 22 and then Shaoxing further south on February 4 where Emperor Gaozong was almost captured by Wuzhu at Mingzhou near Lin'an but Zhang Jun, another general who briefly halted the Jin advance, giving Emperor Gaozong the chance to flee the city by ship. Soon, the Jurchens gave up the pursuit and retreated north. After they plundered the undefended cities of Hangzhou and Suzhou, they finally started to face resistance from Song armies led by Yue Fei and Han Shizhong. In 1130, during the Battle of Huangtiandang, when fleeing to the south, he had the newly appointed commander-in-chief, Yue Fei, who was only 27 years old at the time, to help with the defense, and Yue scored a major victory against the Jin armies neared Nanjing. After the Song forces defeated the Jin, they stayed north of the Yangzi River, and Emperor Gaozong declared the city of Lin'an as the dynasty's new temporary capital, replacing Kaifeng in 1133. Having no surviving sons of his own, he adopted two boys in 1133: one of them became the foster son of the future Empress Wu in 1140, and the other one in 1142. Invasion of Da Qi Reluctant to let the war drag on, the Jin decided to create Da Qi (the "Great Qi") in 1130, their second attempt at a puppet state in Northern China. The Jurchens believed that this state, nominally ruled by someone of Han Chinese descent, would be able to attract the allegiance of disaffected members of the insurgency. The Jurchens also suffered from a shortage of skilled manpower, and controlling the entirety of northern China was not administratively feasible. In the final months of 1129, Liu Yu (; 1073–1143) won the favor of the Jin Emperor Taizong. Da Qi had more autonomy than the previous Da Chu although Liu Yu was obligated to obey the orders of the Jurchen generals. With Jin support, Da Qi invaded the Song in November 1133. Li Cheng, a Song turncoat who had joined the Qi, led the campaign. They initially had success as Xiangyang and nearby prefectures fell to his army.
