Fetal bones were taken out 38 years after the death of an Indian woman’s ectopic pregnancy.

　　Caste is a slightly taboo topic in India. If you talk to Indians about the topic of caste, many people will reply that the caste system has died, but some Indian scholars believe that the caste system can be said to be the core of Indian society to some extent. Today, Indians’ identity cards do not indicate their caste class, but in life, Indians have a set of "skills" to distinguish caste.

　　It’s not reliable to judge a person by his appearance.

　　There are four castes in India: Brahman, Khrushchev, Vedas and sudra, which are arranged from high to low, and some people’s castes belong to the untouchable class, which is called Da Park Jung Su. Tracing back to the source, castes were originally distinguished according to people’s skin color and occupation, and the whiter ones were the superior Aryans, which were high castes; Dark-skinned people are generally inferior or Dravidian, belonging to low caste. The priests and monks are Brahmins, the kings and warriors are Khrushchev, the merchants and craftsmen are Vedas, the peasants and laborers who serve the above three classes are sudra, and da Park Jung Su is engaged in dealing with unclean things such as feces and corpses. However, this was thousands of years ago. With the development and change of society, the division of labor has become more detailed, the migration of people has become more frequent, and the intermarriage between castes has gradually increased, resulting in thousands of sub-castes, such as grazing caste, brewing caste, oil-extracting caste and so on.

　　Nowadays, it is not reliable to judge the caste of Indians only by their skin color or occupation. For example, Modi, the current Prime Minister of India, is relatively fair-skinned among Indians, and he is the head of state. How can he be a Brahman or a Khrushchev class? Wrong! Modi was born in the sub-caste of "Ganqi" in Gujarat, and was an absolute low-caste disadvantaged group. There is a famous Indian singer named Hans Raj Hans. He has a charming long curly hair with a slight golden color, and his skin is as white as that of a European. However, he is a da Park Jung Su.

　　The shoe in hand is Da Park Jung Su.

　　In terms of diet, generally speaking, high-caste people are more vegetarians, while low-caste people are more non-vegetarians. Wealthy Brahmins generally don’t eat and drink. Their diet tends to be light and fresh, and they like to eat fresh fruits and vegetables and grain at that time. The reporter once had lunch with the president of a famous university in India. This meal left a deep impression on the reporter, because it was completely different from the printed meal in the restaurant outside. The meal provided by this Brahmin family was very light and healthy, and even the curry tasted fresh rather than spicy, which can be said to be very in line with the standards of healthy meals in China. On the contrary, some poor families in Da Park Jung Su have a small amount of food and a heavy taste for economic reasons. In addition, among the people who drink alcohol in India, there are more people of low caste, which is probably related to their high-intensity manual labor and more social pressure.

　　In modern cities, it is difficult to distinguish Brahmins from Da Park Jung Su simply by their clothes. In some remote and backward villages or in the past, Da Park Jung Su was still discriminated against in dress. For example, da Park Jung Su was asked to carry a bag with him when he went out in ancient times. The purpose of this bag was to hold their own excrement, for fear that their excrement would pollute the land in the village. In addition, when Da Park Jung Su traveled during the day, he had to ring the bell in advance to remind people to avoid it, because according to the canon, even if people of high caste didn’t touch Da Park Jung Su, just seeing them was also a kind of pollution. Therefore, da Park Jung Su tends to wrap himself more in clothes and expose his face and body as little as possible.

　　Even today, in some villages, if you see someone walking or riding a bike with their shoes in their hands instead of on their feet, it must be Da Park Jung Su. Because according to the regulations, da Park Jung Su must be barefoot and not wear shoes when passing through the residential area of high caste people.

　　From people’s demeanor, we can also see the clues of some caste classes. People with high castes are generally more confident and will look you straight in the eye when they meet; Da Park Jung Su tends to feel inferior and shy, and his eyes twinkle and he looks around or stares at the ground. Take taking photos, for example. The reporter found that most Indians he met liked you to take photos of him/her. What impressed me deeply was that once when taking pictures in the park, some girls were very cheerful and generous, posing in various poses for you to take enough pictures; A woman hiding in a corner in shabby clothes pulled up her scarf to cover her face when the camera was aimed at her.

　　From people’s language and speech, we can’t absolutely tell the caste level, but there is also a problem of probability. People of high caste have a higher chance of receiving a good education and often speak fluent English; However, few people in Park Jung Su have the opportunity to receive a good education. Most of them can’t speak English and can only communicate in the local language.

　　"anonymity" dilutes caste traces

　　It is generally believed that the caste system is based on the teachings of Hinduism and exists only among Hindus who account for more than 80% of India’s population, including many Indians. However, after investigation, the reporter found that the caste system has penetrated into every corner of Indian society for thousands of years. Among Sikhs, Muslims and even Catholics in India, although their teachings advocate equality for all, caste differences and even caste discrimination still exist. An Indian Muslim answered this question very cleverly, saying that "Islam has no caste, but Indian Muslims do".

　　Generally speaking, knowing an Indian’s surname plus some other factors such as occupation, appearance, accent, etc., can basically judge his caste. However, it is not safe to infer caste from surnames. In India, there are also special cases in which Hindus with lower castes convert to other religions and even change their surnames. In the workplace, people will consciously dilute the traces of caste. Some people with relatively low castes like to take some small measures of "anonymity", such as calling themselves "Kumar". The reporter once called the Indian Ministry of Foreign Affairs to find a staff member Kumar. Laughter came from the other end of the phone and said, "There are more than a dozen Kumar in our office. Who do you want?"
