Why did Gan Long execute three trusted ministers at the same time in the first "Jinchuan Battle" in the Qing Dynasty?

In the first "Battle of Jinchuan" in the Qing Dynasty, Qianlong executed Zhang Guangsi, the governor of Yunnan and Guizhou, and three ministers, namely, Neiqin, Qingfu and Qingfu. I think I deserve to die. When he couldn't beat the other side in the battle of Jinchuan, he teamed up with the other side to lie about the military situation, which also led to many wars in Jinchuan later. Zhang Guangsi and Neiqin suffered many defeats in Jinchuan campaign, and their internal discord delayed their fighters.

Sichuan-Tibet Qing Dynasty always adopted the strategy of "controlling foreign countries with foreign countries". Looking to the right is the main road to Sichuan and Tibet. The place is very small, everyone lives in Tibet, and the terrain is steep. Because the governor of Sichuan and Shaanxi, Qing Fu, and the governor of Sichuan, Ji Shan, misjudged the area and reported incomplete information to the court, Gan Long agreed to send troops to this area, but Gan Long repeatedly told Qing Fu not to underestimate his enemy, but Qing Fu did not take it to heart, which was too arrogant.

After the Qing army arrived in the local area, it was dumbfounded. Because the Qing army was unfamiliar with mountain operations and the terrain was steep, it was difficult to guarantee the supply in the rear, and the war lasted for 8 months and there was no chance of winning.

After seeing this situation, Qingfu was afraid that there was no way to explain it, so he reached an agreement with the enemy, lied about his military situation and went back to the court to get the credit. Although Gan Long had doubts about this result, there was no evidence and he didn't say much. Later, the murder of Qingfu included this matter. Qingfu not only failed in the battle, but also let the restless forces in Jinchuan see the incompetence of the Qing government, which led to many wars in Jinchuan later.

Jinchuan is divided into large and small Jinchuans, ruled by two different forces. Later, the forces of the Great Jinchuan controlled the Small Jinchuan through the honey trap, which threatened the Qing government. Qianlong sent Zhang Guangsi, governor of Yunnan and Guizhou, to pacify it. At first, we made achievements through various methods, but we never won. Gan Long sent Nekhin to Jinchuan again, but the discord between Zhang Guangsi and Nekhin led to no progress in the war. Gan Long was so angry that Zhang Guangsi and his back office were executed. Fu Heng was sent after the Battle of Jinchuan. Because it lasted too long, Sharon showed weakness first and ended the war.
