What was Song Gaozong doing when the Jingkang Rebellion happened?

In the first year of Jingkang in the Northern Song Dynasty (A.D. 1 126), Jin Jun captured Kaifeng (now Henan), the capital of the Northern Song Dynasty. In February of the following year, the emperor was abolished, Qin abolished the emperor, and the Northern Song Dynasty perished. In May of the same year, Kang Wang and Zhao Gou, the former marshal of Hebei military forces, acceded to the throne in Nanjing (now Shangqiu South, Henan Province) after the defeat of the 8 Jin Army, and they still used the title of Dasong, which was called the Southern Song Dynasty in history. During the Southern Song Dynasty, it was imperative to select and appoint talents, innovate military and political affairs, and make proactive strategic plans. However, Song Gaozong was incompetent, so Li Gang, who rejected sages by employing people, changed the policy of active resistance to passive defense. As a result, it was difficult for Li Gang to fully implement the ten principles of the founding of the People's Republic of China, and the Kaifeng House base operated by Zong Ze was abandoned, which dealt a blow to the activities of the Central Plains against Jin Yijun. Subsequently, Song Ting adopted the strategy of abandoning Huai River and fleeing to Lin 'an in the south. As a result, Lin 'an Guards staged a coup, and 8 Jin Army also took the opportunity to go south. Song Gaozong set sail to avoid disaster, and the Southern Song Dynasty almost perished. Jin Jun pursued Song Gaozong, but it retreated from the south to the north. Huang Tiandang was stopped by the Han Shizhong Department of the Southern Song Dynasty, and the withdrawal of Jin Jun from the North was doomed. Since then, Jin Jun did not dare to cross the river easily, and the Southern Song Dynasty imperial court was able to stand in the south of the Yangtze River.
