Zhou Enlai's Death

Zhou Enlai was the top CCP operative in Shanghai and too high-profile a person to be taken down so brazenly. Zhou escaped to Wuhan and met with Wang Qing Wei and Chandu Shou, but to no avail. The manner in which the operation was carried out left no doubt in anyone's mind that this united front or first united front was over. And Soviet cooperation with the Guomindan, you'd forget about that too.
