Indian caste system divides people into four different classes: Brahman, Khrushchev, Vedas and sudra. Brahman is a monk, the first caste, the highest status, engaged in cultural education and sacrifice; Khshatrili is a soldier, a prince, a nobleman, etc. As a second caste, engaged in administrative management and fighting; Vedas are merchants, the third grade, engaged in commercial trade; Sudra, a farmer, the fourth caste, has the lowest status, and is engaged in agriculture and all kinds of manual and handicraft labor. Later, with the development of production, many grades were derived from various surnames. In addition to the four castes, there is another kind of people who are excluded from the caste, namely "Dalits" or "Dalits". They have the lowest social status and suffer the most discrimination. Most of them are poor peasants and farm workers in rural areas, cleaners and coolies in cities.

Negative: the boundaries between castes are strict, so you can't marry, and you can't eat and sit together at the door of communication.

People of high caste have conflicts with people of low caste. If people with low castes use a certain part of their bodies to cause harm to people with high castes, they must cut off the body parts that cause harm to people. The low caste with low status insults the high caste, and those who are light are severely punished, and those who are heavy are tortured. If a man of high caste kills a sudra, he will only pay with livestock. People are used to the fact that people with high castes cannot eat and live together, and intermarriage between castes is prohibited. People of high caste may be sentenced to death if they marry people of low caste, especially Dalits.

In every caste, there are people who supervise the people of this caste to abide by the Manu code and traditional customs. If there are violators, they will be punished by Brahmin priests, or expelled from the caste and become untouchables.
