Financial affairs

But she said she had felt scared about having a family.

"I was not sure whether I was ready to give birth to and raise a baby," she said.

"I was also worried about our finances. Questions of whether we were capable of supporting a family kept haunting me and made me nervous."

But her husband was running his own business and earning good money, which helped her to decide to get married.

Zhou, from Baihe.com, said finances play a key role in marriages.

She suggested undergraduates ensure they can feed themselves and run a family before deciding to marry.

"Otherwise, they may soon encounter a crisis in married life," she warned, adding that marriage is not only about love and romance but more about making a lasting promise to the partner and maintaining a family together.

"Most undergraduates rely totally on their parents before graduating and entering society. They are unable to afford a family of their own under such circumstances and are therefore unable to make real promises to their partners," Zhou said.

Shen Ying, a senior marriage expert at Jiayuan.com, a leading dating website in China, said some undergraduates who marry while at college do not realize the difficulty of making a living and running a family until they graduate.

"Life is not easy, especially when you first enter society as a fresh graduate," Shen said. "Couples who marry at university may have disputes over economic issues if they are not financially prepared."
