? What is family relations ? 什么是家庭關系 ? In human context, a family (from Latin: familiare) is a group of people affiliated by consanguinity, affinity, or co-residence. In most societies it is the principal institution for the socialization of children. Extended from the human “family unit” by biological-cultural affinity, marriage, economy, culture, tradition, honour, and friendship are concepts of family that are physical and metaphorical, or that grow increasingly inclusive extending to community, village, city, region, nationhood, global village and humanism. A family group consisting of a father, mother and their children is called a nuclear family. This term can be contrasted with an extended family. ? There are also concepts of family that break with tradition within particular societies, or those that are transplanted via migration to flourish or else cease within their new societies. As a unit of socialization and a basic institution key to the structure of society, the family is the object of analysis for sociologists of the family. Genealogy is a field which aims to trace family lineages through history. In science, the term “family” has come to be used as a means to classify groups of objects as being closely and exclusively related. In the study of animals it has been found that many species form groups that have similarities to human “family”―often called “packs”. ? Marriage is a social union or legal contract between people that creates kinship. It is an institution in which interpersonal relationships, usually intimate and sexual, are acknowledged in a variety of ways, depending on the culture or subculture in which it is found. Such a union, often formalized via a wedding ceremony, may also be called matrimony. ? 夫妻一體主義（doctrine of integrated conjugal personality）也稱夫妻同體主義，是指男女結婚后，夫妻合為一體，夫妻的人格（personality）相互吸收。但實質上是采用夫權主義(masculinity)，妻之人格為夫之人格所吸收，妻子的活動由丈夫代表，妻子喪失民事法律行為(civil legal act)能力及訴訟(litigation)行為能力及管理、用益和處分自己財產的能力等。19世紀以后西方各國的夫妻立法采取夫妻別體主義(doctrine of separate conjugal personalities)。夫妻別體主義是指夫妻結婚以后男女平等，各自保有獨立人格，夫妻平等享有民事法律行為能力、訴訟行為能力、對財產享有所有權（proprietary rights）的能力及對個人財產擁有管理、用益和處分的能力以及參加社會活動的能力等。 ?
