power struggle intensified over time as Sun He and Sun Ba started vying for their father's favour and attention. Two opposing factions also emerged from among Sun Quan's subjects: On one side, Lu Xun, Zhuge Ke, Gu Tan, Zhu Ju, Teng Yin, Shi Ji, Ding Mi () and Wu Can believed that Sun He was the rightful heir apparent so they supported him. On the other side, Bu Zhi, Lü Dai, Quan Cong, Lü Ju, Sun Hong (), Quan Ji (), Yang Zhu (), Wu An () and Sun Qi () supported Sun Ba.

After carefully considering some time, Sun Quan ordered Sun He to be put under house arrest. When Zhu Ju, Qu Huang () and some other officials heard about it, they covered their heads in mud, tied themselves up, and came
