Based on the data of five large-scale sampling surveys on Guangzhou youth in recent ten years，this chapter focuses on the youth’s attitudes toward mate choice，marriage，fertility，sex and behaviors of establishing dating and marriage relationship，giving a comprehensive analysis on the changes of Guangzhou youth’s attitudes toward love and marriage，and summarizing the main features and changing tendencies of Guangzhou youth marriage and loving attitude development in the recent ten years. On this basis，this chapter raises recommendations. The research notices that young people are facing conflicts between the traditional and modern views regarding love and marriage，leading to some confusions；in the meantime，young people are more tolerant and rational，making their views in this aspect more realistic and diverse. Young people in general can accept premarital cohabitation，but at the same time the rate of phenomena like flash marriage，puppy love，unmarried abortion and so on is in distinct raise. The marriage of young people has insufficient stability.
