 The Jin leadership had not expected or desired the fall of the Song dynasty . Their intention was to weaken the Song in order to demand more tribute , and they were unprepared for the magnitude of their victory . The Jurchens were preoccupied with strengthening their rule over the areas once controlled by Liao . Instead of continuing their invasion of the Song , an empire with a military that outnumbered their own , they adopted the strategy of " using Chinese to control the Chinese " . The Jin hoped that a <unk> state would be capable of <unk> northern China and collecting the annual indemnity without requiring Jurchen <unk> to quell anti @-@ Jin uprisings . In 1127 , the Jurchens installed a former Song official , Zhang Bangchang ( <unk> ; <unk> – 1127 ) , as the puppet emperor of the newly established " Da Chu " ( Great Chu ) dynasty . The puppet government did not deter the resistance in northern China , but the insurgents were motivated by their anger towards the Jurchens ' looting rather than by a sense of loyalty towards the inept Song court . A number of Song commanders , stationed in towns scattered across northern China , retained their allegiance to the Song , and armed volunteers organized militias opposed to the Jurchen military presence . The insurgency hampered the ability of the Jin to exert control over the north .
