Passage:In November 1911, after the start of the Xinhai Revolution, he returned to Shanghai, where he became local leader of the Tongmenghui movement in the city. However, he disagreed with Song Jiaoren over the establishment of the Kuomintang, and left China for Belgium, where he earned degrees in medicine and pharmacology at the Free University of Brussels, but he never went into medical practice. He returned briefly to China in 1915 to oppose Yuan Shikai's attempt to establish a new Chinese Empire, but soon returned to Europe.
