The marriage ceremony of a young Chinese couple, both aged 16, has gone viral on the Internet.

The legal age for marriage in China is 22 for men and 20 for women, which means they'll have to wait another six years before they can be legally married in the eyes of the law.

The "groom", surnamed Zhang, and the "bride", surnamed Wu, are both from southwest China's Guangxi Zhuang Autonomous Region.

The boy quit his high school studies in Year Two and has been working in Nanning, the capital of Guangxi; and his partner, Wu, also dropped out of school last year.

Zhang said online that he didn't regret leaving school at such a young age and said that they "love each other truly."

The vast majority of internet users have shown their support for the "marriage."
