Shaolin monks also belong to monks, and shaving their heads is a monk's ceremony.

In the 5th century BC, in a Sakyamuni tribe on the border between Nepal and India, Prince Gautama Fandado left home to practice. Seven years later, he became a Buddha and began to preach and recruit disciples in the Ganges valley. Buddhism believes that the world is illusory and life is suffering. Only by cutting off all troubles and practicing Buddhism can we get eternal happiness. When Buddha Sakyamuni first told Ye Jia and five other people, he personally shaved their hair and accepted them as disciples. A monk shaving his head has three meanings. First, according to Buddhism, hair represents countless troubles and wrong habits in the world. Cutting off hair is equivalent to removing troubles and wrong habits; Second, cutting off the hair is equivalent to removing the pride and neglect of the world; Get rid of all troubles and practice wholeheartedly. In ancient China, people regarded hair as very important, thinking that it was obtained from parents, so it must be protected and not damaged, otherwise it would be disrespectful to parents. Buddhism demands that these unnecessary family concerns be cut off; The third is to distinguish other sects in India. At that time, India was full of sects. But when people see a bald head, they know it's a Buddhist. Later, shaving became a Buddhist ceremony.

When Buddhism was first introduced to China, other rituals were not developed. You can become a monk by shaving your hair and putting on coarse clothes like cassock.
