Chinese kinship

The  中文:亲属系统, system is classified as a  system (also referred to as the "Descriptive system") used to define. Identified by in his 1871 work Systems of Consanguinity and Affinity of the Human Family, the Sudanese system is one of the six major kinship systems together with, , , , and.

The Sudanese kinship system (and hence the Chinese kinship system), is the most complicated of all kinship systems. It maintains a separate designation for almost every one of 's kin based on their generation, their lineage, their relative age, and their gender.

In the Chinese kinship system:
 * Maternal and paternal lineages are distinguished. For example, a mother's brother and a father's brother have different terms.
 * The relative age of a sibling relation is considered. For example, a father's younger brother has a different terminology than his older brother.
 * The gender of the relative is distinguished, like in.
 * The generation from ego is indicated, like in English.

Chinese kinship is, emphasising.

Literature and history
Kinship terms have already appeared in the earliest Chinese lexicon . Chapter Four 釋親 is dedicated to explain kinship and marriage. Another lexicon from late  has a detail list of form of address of all relatives.

With the influence of, the concepts of kinship and are deeply ingrained in Chinese culture. One of Confucian teachings is, where it is extended to a series of five relationships known as the Five Cardinal Relationships, (五倫). three of which are related to the family:


 * ruler and subject (君臣),
 * father and son (父子),
 * elder and younger brother (兄弟),
 * husband and wife (夫婦),
 * between friends (朋友)

In the , the nine s are listed in the following stanza:

Culture
In Chinese culture where the extended family is still valued, kinship terms are ensured to survive well into current usage. Also, since it is to refer to or address a more senior family relation by his or her given name, the kinship term is the only possible term of address. In the case where there are multiple siblings such as found in many families, the relation is distinguished and addressed according to their age or rank. For example 大 (great/senior/elder) is address for 大姨 (the eldest sister of one's mother); 二姨 (the 2nd eldest sister of one's mother); 三姨 (3rd eldest sister of one's mother) etc.

Because some of these terms have no equivalent in foreign languages, they are not easily translated and the descriptiveness often lost in translation.

Law
The  (《大清律例》) was the last set of Chinese laws where the complete kinship terms were shown. The code not only confirmed the importance of defining kinship relations, but also defined the legal and moral conducts between family relations. Although there was no specific statute in the Qing code to define kinship terms, it specified the attire and  appropriate according to the relation between the mourner and the deceased. Kinship relationships also played a crucial role in the administration of justice under the Qing. Penalties were more severe for crimes committed against senior relatives within the family hierarchy. Crimes committed against those outside of the extended family were punished less harshly. Crimes committed by senior family members against their inferiors were least likely to elicit harsh sentences.

Among the 47 s added in 1740 under, Statute 2 (Charts/Tables of Mourning Attire, 《喪服諸圖》) and Statute 3 (Code of Attire, 《服制》) dealt with mourning attire completed with charts. According to Qing law, one had to observe a period of mourning when a relative died. The closer and more senior the deceased family member, the longer the period of mourning is dictated by law. The mourning period range from three months to three years. During this period, the bereaved had to stay at home, excuse himself from public service, refrain from celebrations of all sorts, and practice abstinence, among other things.

The "extermination of nine kindreds" (誅九族) is considered one of the most severe punishments found in traditional Chinese law enforced until the end of Qing. The practice of exterminating the kins had been established since when Emperor  (reigned –) declared "Those who criticize the present with that of the past: Zu" (以古非今者族). Zu (族) referred to the "extermination of three kindreds" (三族): father, son and grandson. The extermination was to ensure the elimination of challenges to the throne and political enemies. (reigned –) abolished the practice but it was reintroduced by succeeding (reigned –). Not only did he bring back the punishment, but he also extended it to the nine kindreds.

In the first year of reign of  (reigned -), prominent historian Fāng Xìao-rú (方孝孺) elicited the offense worthy of the "extermination of nine kindreds" for refusing to write the  and for insulting the Emperor. He was recorded as saying in defiant to the would-be Emperor: "莫說九族，十族何妨！" ("Nevermind nine agnates, go ahead with ten!"). Thus he was granted his wish with perhaps the only and infamous case of "extermination of ten kindreds" (誅十族) in the history of China. In addition to the blood relations from his nine-agnates family hierarchy, his students and peers were added to be the 10th group. Altogether 873 people was said to have been executed.

To this day, a three-character Cantonese term citing the "death to the entire family" remains a powerful term in the.

Clan
A Chinese clan is a patrilineal and patrilocal group of related Chinese people with a common surname sharing a common ancestor. In southern China, clan members could form a village known as an ancestral village. In Hong Kong, clan settlement is exemplified by. An ancestral village usually features a hall and shine honouring ancestral clan members. A clan can be found recording male members of the clan. A married woman is considered part of her husband's clan.

Marriage and divorce
Marriage is an important rite signifying the coming together of two clans, and the beginning of a new family unit.

Polygamy
(specifically ) had been practised in Chinese societies for thousands of years. Since, Chinese men could technically have only one wife. It was common for privileged Chinese men to have a wife and various, however. Those who could afford and supporting a family of multiple concubines and children, polygyny provided a better chance of issuing. The importance of this was apparent in the imperial court usually housing hundreds of concubines. Aside from concubinage, having multiple wives with equal status was also accepted prior to the ban of polygamy.

In a concubinage situation, the wife, concubines and their children would live in the same household. Wives and concubines would often refer to each other as "sisters". As a concubine was not wedded in a marriage ceremony, she had fewer rights in the household. There was also no inter-clan relation between the man's clan and the concubine's own kin.

Polygamy was banned in China in 1930 when the government promulgated Civil Code (Part IV) where Section 985 states "A person who has a spouse may not contract another marriage. A person shall not marry with two or more persons simultaneously." . This is still in effect today in the territories under effective administration of the Republic of China including Taiwan and Kinmen and Matsu. After the establishment of the People's Republic of China by the Chinese Communists on the mainland, this banning is reaffirmed in the passage of the Marriage Code of 1950. In, new polygomous marriages were no longer legally allowed after 1971 with the passage of the Marriage Act. Despite this, incidents of extra-marital affairs are rising. Some men have even established a family with their mistresses and children kept secret to their wives. There is a phenomenon of cross-border polygyny usually involving Hong Kong men and their mistresses living in Mainland China.

Demographics
With modern Chinese governments advocating for smaller families through family planning campaigns and policy-making, large extended family may be a thing of the past. The introduced its  in 1979 while The Family Planning Association of  began its "Two is enough!" (兩個就夠哂數!) campaign in the. Contrasted with the large extended families created over pre-war and baby boom years, the average modern Chinese families now have much fewer children.

As of 2006, the s in Hong Kong and  in the world. Hong Kong, ranked the lowest in the world, was the only territory with less than one child born per woman on the average. Both Mainland China and Taiwan were ranked well below the world. Similarly, the s in Hong Kong and Macau in the world. Both Mainland China and Taiwan were ranked below the.

A product of rising divorce rates in Chinese societies is the breakdown of the traditionally close-knitted kinship relation. On the other hand, re-marriage could provide more than two sets of paternal or maternal relatives.

Nine grades of relations
The "nine grades of relations" (九族) is an important concept when it comes to application of laws and observing rituals. Since the, there have been two separate interpretations of what is defined by the nine grades. Each interpretation is based on societal and political needs as the ruler of the day see fit.

The "older" interpretation ("古文說") defined the nine grades of relations strictly in the paternal line. That is, nine generations from great-great-grandfather down to great-great-grandchildren. This interpretation was officially recognised after and  dynasties. By and  dynasties, laws have defined the  of the nine kindreds. This interpretation was cited in Part III Chapter 2 of 's 1877 book Ancient Societies.

The "contemporary" interpretation ("今文說") defines the nine grades of relations to be four generations from the paternal line, three from the maternal line, and two from the wife's. Historically, this definition has been used during award, punishment and family annihilation.

Yet another interpretation suggests that "nine" is actually an arbitrary number as nine is considered a large number in Chinese culture. As such, it means anyone and everyone related is to be executed in the context of family annihilation.

Five degrees of mourning attire
The (五服) defines not only the proper attire, but also the proper mourning ritual one should observe when a relative has died. Appeared in as early as the , mourning rituals developed over the years. By Qing dynasty, it was set in law that there were five degrees, or grades of mourning according to the relationship one has with the deceased. The closer a person is related to the deceased, the higher degree of mourning is observed. A married female belongs to her husband's clan and observes similar but lower degree of mourning as her husband. She would observe mourning for a small portion of members from her own clan. A married man would observe mourning for even less number of relations of his in-laws.

In a concubinage situation, a concubine was only required to mourn for her husband, his wife, his parents, and all his children including her own, whereas a wife was required to mourn for almost all of her husband's near relatives. In addition, there was no requirement to mourn the death of a concubine except by the man's children.

Since the end of feudal China, the rituals of the five degrees of mourning have largely given way to simpler and less elaborate observance.

Conventionally, clans adopted the five degrees of mourning as an unwritten definition between close and distance relatives. As such, marriage between relations that were covered within the five degrees of mourning was considered taboo and immoral. This definition, unlike the mourning ritual, is still applicable in determining whether a marriage is acceptable, albeit less people are familiar with the mourning rituals themselves.

It must be noted however that by according to this rule, many relatives considered as "distant" in Western cultures are counted as close relatives in Chinese culture.

The five degrees of mourning attire in the decreasing order of severity are:
 * 1. 斬榱 - 3 years
 * 2. 齊榱 - 3 years, 1 year, 1 year with staff of mourning, 5 months, 3 months
 * 3. 大功 - 9 months, 7 months
 * 4. 小功 - 5 months
 * 5. 緦麻 - 3 months

Common extended family and terminology

The terms are listed in, regional and dialectal usages are listed in the corresponding row. The degrees of mourning attire are included as an indication of how close the relation is to ego and what level of respect is expected. "1" being the highest; "5" being the lowest. "0" means they are not within the definition of the five degrees of mourning. Some of these are common relations and are included for completeness. The degrees of mourning indicated in the table are based on ego as an unmarried member of the family.
