Because his favorite queen is dead. Gan Long especially liked the Filial Piety Queen, but the Filial Piety Queen was in poor health and died. Gan Long was heartbroken and almost cried. I think unforgettable love is probably like this. Then he ordered everyone not to shave their hair for 100 days to show their respect for the queen.

However, some officials are used to obeying other people's orders, so they won't listen to what Gan Long says, so some people secretly shave their heads. Gan Long was very angry when he heard that these people didn't know that the gun had hit the first bird? Or do you think I'm kind and won't even listen to me? So he ordered that all officials who shaved their heads should be put to death, which was completely non-negotiable. Among the people who were executed this time, there were officials like the governor of Hunan, which seemed to really violate the emperor's taboo.

Later, because of the failure in Jinchuan, Gan Long became more angry, and then three military officials were executed by him. This is what makes Gan Long particularly clever. After he killed these people, he began to rectify the discipline of the army and often went to see the army when something happened. If you lose the battle, your head will definitely move around your neck, and it's useless for anyone to intercede.

Gan Long's iron and blood skills improved the Qing army qualitatively. I believe that Qianlong is not a fatuous emperor, and those officials who were killed for shaving their heads are not as simple as they seem. By shaving his head, Qianlong put an end to the duplicity of officials, which can be said to eliminate the atmosphere in officialdom. But then again, being an official in ancient times was really a very dangerous thing, because you really didn't know that you just did one thing and let your head move.
