Nanchang Uprising
In October 1927, the Comintern asked the CCP to organize a delegation to Moscow to attend the celebration ceremony of 10th anniversary of the October Revolution. Many CCP leaders had taken refuge in Guangdong and Hong Kong after the failure of the Nanchang Uprising, and were still there. Su and Li Weihan were still on their way from Wuhan to Shanghai. This left the CCP central organization in disarray, and Xiang was elected to be the director of the delegation to the Soviet Union.
