Why did Chinese men during this time wear their hair in a long plait at the back of the head and have the rest of their head shaved?

During the Qing Dynasty, Chinese men wore their hair in a long plait, or queue, with the rest of their head shaved as a symbol of loyalty to the ruling Manchu government. This hairstyle was mandated as part of the Manchu's efforts to assert their control over Han Chinese society. Wearing the queue was seen as a demonstration of submission to the new regime, while the shaved head represented a break from traditional Han customs. Non-compliance could lead to severe punishment, reinforcing the importance of this hairstyle during that period.
