Cai E
In 1915, he opposed Yuan's attempt to make himself emperor. He convinced his disciple Cai E, the military governor of Yunnan, to rebel. Progressive party branches agitated for the overthrow of Yuan and more provinces declared their independence. The revolutionary activity that he had frowned upon was utilized successfully. Besides Duan Qirui, Liang was the biggest advocate of entering World War I on the Allied side. He felt it would boost China's status and also ameliorate foreign debts. He condemned his mentor, Kang Youwei, for assisting in the failed attempt to restore the Qing in July 1917. After failing to turn Duan Qirui and Feng Guozhang into responsible statesmen, he gave up and left politics.
