What are the examples of massacres in ancient China?

The list goes on:

"Gao Han Ji Yi" records that Liu Bang sent people to crusade against Zhou Yin, the great Sima of Chu. Zhou Yin could not resist the temptation of Liu Bang and betrayed Chu. He led the troops to slaughter the people in six places, and led the troops to Qing Bu, the general of Liu Bang, in Jiujiang to slaughter his father with him. In the end, only Lu was not captured. Liu Bang was furious and wanted to mobilize people from all walks of life to carry out a bloodbath in the local area.

"Historical Records Hou Zhoubo's Family" records: Chen Yi rebelled, Liu Bang ordered Zhou Bo to lead an army to crusade against Chen Yi, and Zhou Bo killed Mayi City guarded by Chen Yi; Lu Wan, the prince of Yan, rebelled, and Zhou Bo, as the prime minister, led the army to counter the rebellion instead of Fan Kuai and slaughtered the muddy capital of Lu Wan.

According to Geng Yan, Geng Yan, as a general, pacified 46 counties and slaughtered 300 people, never losing.

According to the biography of the reflection of Wei Zhi Yu Xun, since Dong Zhuo's rebellion in Beijing, the people in the city have retreated eastward, mostly staying in Pengcheng area. Cao Cao led the army to this point, killing tens of thousands of men and women and throwing them into Surabaya, causing Surabaya to be cut off. Tao Qian, Cao Cao's father-killer, led the troops stationed in Wuyuan. Cao Cao could not advance, so he led his troops to capture Suiling, Xiaqiu and other counties from the south of Surabaya. Wherever you go, you are slaughtered, leaving no chickens or dogs and pedestrians in the city. Attention source
