There is an interesting twist on matrimony. To tie the knot, two couples in Jinan city have taken the plunge. You may need swimming lessons if you want to get married like two couples in eastern China's Shandong province. They tied the knot underwater at Marine Park surrounded by fish.

The couples donned scuba gear over their formal clothes before diving in as hundreds of spectators watched from the aquarium's "Underwater Theatre."

"It was romantic and breathtaking."

And this will be an unforgettable moment for the new couples.

Chen Xi & Li Zhe, the bride & groom, said, "It was beautiful - so many mermaids were around us."

"I saw schools of fish swimming around us and I will never forget this experience my whole life."

The wedding planner said the group required special training for the event. And the lucky couples were also entertained by singing sea lions and received kisses from dolphins. Hopefully nobody gets jealous.
