Next, the Zhili clique started a national campaign to restore Li Yuanhong as president. Despite having co-existed with Xu Shichang for two years after the fall of Duan, they declared his presidency illegal as he was elected by an illegal parliament. They demanded Xu and Sun Yatsen resign their rival presidencies in favor of a unified government.

Enough members of the old parliament moved to Beijing to constitute a quorum which superficially gave the government an appearance that it operated as it did before the Manchu Restoration in 1917.
