【正确答案】The structure of the family, which is a basic unit of the society, changes along with the development of the society. In China's feudal society which lasted several thousand years, a self-sufficient economy predominated. The family was not only a basic unit in everyday life, but also a basic unit of production. At that time, an ideal and admirable family consisted of five generations, with the male members making the important decisions. During the last hundred years, great changes have taken place in China. The Chinese society has gone through the long feudal period and turned into a socialist society. This historic change has led to changes in the Chinese family structure. Extended families consisting of many family members begin to be divided into smaller families and stem families, with the trend pointing toward the emergence of more and more nuclear families.
