Song Jiaoren
After Yuan Shikai became the President of the Republic of China in 1913, Zhang was his high-ranking advisor for a few months until the assassination of Song Jiaoren. After criticizing Yuan for possible responsibility of the assassination, Zhang was put under house arrest, in Beijing's Longquan Temple, until Yuan's death in 1916. After release, Zhang was appointed Minister of the Guangzhou Generalissimo (大元帥府秘書長) in June 1917.
