(16)For newlyweds in China, having a new apartment and car are part of the prerequisites for getting married. But in recent years, as the cost of living goes up, a new notion called “naked marriage” has arisen. It has become a new trend for many contemporary young people in China. (17)With this small marriage certificate in hand, a lifetime of commitment and more responsibility can be expected. And for couples in a naked marriage, this certificate also encompasses other meanings.
Yang Shijin, Chengdu resident, said, “There are many people like us born in the 80’s. Our families cannot afford to buy us new apartments, cars, diamond rings. I think that’s very normal for regular families. We must rely on our own to forge a better future for ourselves.”
Sun Wenkui is working on his Ph.D. in Biology at Sichuan University and lives in a rented place with his wife. He and his wife married in 2011. (18)Unlike other couples that have luxury sedans pick up their brides during the wedding ceremony, Sun used eight tricycles. With neither a new car nor a new apartment like other married couples in China, they live in this small room. Sun says their relationship is simpler than a marriage with a well prepared material foundation. Sun Wenkui, Ph.D. student of Sichuan University, said, “The most important part of a relationship is love. I believe our living conditions will gradually get better.”
Professor Hu says “naked marriage” is in sharp contradiction with China’s established marriage customs, which encourage parents to help lay the material foundation for their children’ s marriage.
