Marriage is the union of two peoples and consequently of two families and two cultures. In traditional Chinese society, everybody gets married for the sake of family continuity. This is because bringing forth a child is seen as a contribution to perpetuate family name. It is meant for two as families to seal stronger bonds together. It's therefore observed that, marriage in Chinese Society is conceived for the families rather than for the sharing love. Consequently, the marriage becomes a social construction. The only credible unions with the eyes of the society were those which linked two individuals presenting some similarities from the social, ethnic, racial, cultural and/or religious. The concept of adaptation and the notion of entropy will be employed the theoretical level to show that mixed marriages are the result of complex processes tending to homogenize populations who are from different cultures but who live in permanent contact. To collect the qualitative, we have used the methods of data-gathering, such as documentary review, individual and institutional interview using the guides of interview.
