A pair of newlyweds in Qingdao, Shandong Province, paraded through the city in a locksmith`s car on Monday, to commemorate the role lock-picking played in their relationship.

The groom, surnamed Zheng, works for a local lock-picking company. Last October Zheng received a call from a woman surnamed Li who needed help opening a locked door.

Li was impressed by Zheng`s intelligence, kindness and patience. They developed a serious relationship shortly after that.
