What happened to Kaifeng when Juchen forces captured it in 1127?

When Juchen forces captured the Chinese capital of Kaifeng in January 1127, the city suffered an orgy of looting and wanton destruction. The fate of the population was severe, as survivors were subjected to cruelties, rape, or sold into slavery.1

The imperial family was also targeted during this event, known as the Jingkang Incident. Song Emperor Qinzong was taken captive and carried off to the Juchen heartland, where he lived the remainder of his life in the status and dress of a servant. This conquest effectively ended the Northern Song dynasty's control over northern China, leading to the establishment of the Southern Song dynasty under a new emperor, Zhao Gou, who ruled from a more defensible location in the south.12
