### The first Military Governor of the Sichuan

The revolutionaries established the Great Han Sichuan Military Government (大漢四川軍政府) in Chengdu, Pu Dianjun who was the Chairman of the Sichuan Provincial Assembly became the Military Governor. Yin Changheng became the Director of War under Pu's direction. But on 8 December a part of the Sichuan Army rose in rebellion at Chengdu because of the delayed payment of wages, Pu escaped from Sichuan. Yin commanded his army and quelled the insurgent troops quickly, so he succeeded Pu's position by the backing of public opinion. On 22 December Yin captured Zhao Erfeng and executed him because of the conspiracy of counter-revolution.
In January 1912, Yin Changheng started to negotiate with Shu Military Government (蜀軍政府) (Military Governor is Zhang Peijue (張培爵)) which was established at Chongqing in November 1911. On 21 March same year both governments agreed to merge with each other and established the new Sichuan Government.

On next month he received the title of lieutenant general. In April 1913 he returned in triumph to Chengdu.

### Downfall and his later years

After returning to Chengdu, Yin Changheng came into collision with his powerful subordinate Hu Jingyi (胡景伊), the commander of an army corps of All Sichuang (全川陸軍軍團長). Hu aspired to replace Yin as Military Governor of Sichuan and approached Yuan Shikai. On 13 June 1913 Yin was transferred to become Administrative Commander in the frontier of Sichuan (川邊經略使), and Hu succeeded into Yin's position. Yin lodged a protest to Yuan, but Yuan's decision did not change. Yin lost his power in Sichuan.
Having thus been sidelined, Yin Changheng lost motivation and in November 1913 went to Beijing on sick leave. In January 1914 the position of Administrative Commander in the frontier of Sichuan was repealed. In a short time Zhao Erfeng's elder brother Zhao Erxun cooperated with Hu Jingyi and intrigued against Yin. On 2 February same year Yin was arrested by the order of Yuan, and he was sentenced to nine years' penal servitude on the charge of murdering Zhao Erfeng.
In June 1916 Yuan Shikai died, and Yin was pardoned. Later he became the Adviser of the Military Governor of Jiangsu, Li Chun. In 1920 Yin became the subordinate of Sun Yat-sen, but in next year he seceded from every political circle and lived in retirement in Chengdu. On the establishing of the People's Republic of China Yin remained in Sichuan. Yin died on 26 May 1953, at Xichang, Xikang.
Writing in 1927, Louis Magrath King, a former British Consul in Sichuan, described Yin Changheng, whom King considered a friend, as a 'philosopher' who "expounded a sort of theosophy all his own, synthesizing the leading religions, Confucianism and Taoism and Islam and Buddhism and the two main divisions of Christianity."
