The governor of Sichuan has a high position and great power. Why does he only care about one province?

Because Sichuan is too big, the situation is very complicated. Although Sichuan is only one province in name, it is actually equivalent to several provinces.

Moreover, although the governor of Sichuan only manages one province in Sichuan, his task is not easy, because some affairs in Tibet are also under his control.

In the early Qing Dynasty, there was no governor in Sichuan. At that time, because most of Sichuan and Chongqing were controlled by Zhang and Nanming governments, the Qing army only controlled northern Sichuan. So there was only one governor in Sichuan at that time, and the headquarters of Futai Yamen was located in Langzhong.

Later, the Qing army defeated Li Zicheng and decided to attack Zhang and Nanming. So the Qing court merged Sichuan, Gansu (including Ningxia and xining in Qinghai today) and Shaanxi, unified under the jurisdiction of the governor of Shaanxi Trilateral, and the yamen stationed in Xi 'an.

As for why the Trilateral Governor's Office was located in Shaanxi, the reason was simple: Sichuan and Gansu were the front lines of Sichuan, Shaanxi and Gansu provinces, and Shaanxi was the safest territory controlled by the Qing court at that time. The money and grain of the Qing army in Sichuan and Gansu should be prepared and distributed by Shaanxi, which is the center of the three provinces.

After more than ten years of tug-of-war, the Ming army gradually withdrew from Sichuan for various reasons, and the Qing army occupied Sichuan.

In the 14th year of Shunzhi (1657), the Qing court moved forward in order to completely destroy Li Dingguo. And moved the front headquarters from Xi 'an to Chengdu.

Due to the promotion of strategic position, the governor's authority was too small, so the Qing court set Sichuan out of the jurisdiction of the governor of Sichuan and Shaanxi, and set the governor of Sichuan in Chengdu.

However, due to the outbreak of the San Francisco Rebellion, Sichuan has once again become a battlefield. Therefore, the large-scale immigration hosted by the imperial court was postponed for more than 20 years, and it was not until the thirty-third year of Kangxi that it officially began.

During this period, due to the need of the war (Sichuan was occupied by Wu Sangui's army), the Qing court set aside Sichuan from the jurisdiction of Governor Chuanhu and returned it to Governor Chuanshan. Since then, Sichuan has long been under the jurisdiction of the governor of Sichuan and Shaanxi.

In the fifty-seventh year of Kangxi (17 18), the Junggar khanate invaded Tibet.

Because the Qing army needed to send troops from Sichuan and Shaanxi to attack Junggar, Sichuan's strategic position was highlighted again. So Emperor Kangxi set aside Sichuan again and appointed Nian Gengyao as the governor of Sichuan.

In the 60th year of Kangxi (172 1), Tibet was recovered, and Sichuan and Shaanxi merged again, renamed Governor of Sichuan and Shaanxi, and Nian Gengyao became Governor of Sichuan and Shaanxi.
