In page Human sacrifice:

"

The ancient Chinese are known to have made drowned sacrifices of men and women to the river god Hebo.[2] They also have buried slaves alive with their owners upon death as part of a funeral service. This was especially prevalent during the Shang and Zhou dynasties. During the Warring States period, Ximen Bao of Wei outlawed human sacrificial practices to the river god.[3] In Chinese lore, Ximen Bao is regarded as a folk hero who pointed out the absurdity of human sacrifice.[citation needed]
