A highly unlikely set of nuptials has taken place in China with a pair of twin brothers marrying twin sisters.

Not only that, both sides have a pair of twin uncles.

A wedding photo featuring four sets of twins went viral online recently, racking up more than 10 million views.

According to the mainland media outlet Jiupai News, the two couples only discovered on the wedding day that their uncles were also twins.

The wedding host called it a “miracle”, and the guests were equally astonished and thrilled.

One villager told the media: “I have lived over 60 years and have never seen anything like this before. I wish them a lifetime of even more happiness.”

According to Jimu News, the two couples, both in their twenties, are from Fuyang, Anhui province, central China.
