A couple tumbled down an escalator at a train station after they kissed each other in China. 

The video, filmed in the city of Taiyuan in Shanxi Province on June 27, shows a man and a woman stepping onto an escalator and then kissing each other. 

However, they lost balance and fell down backwards.

The couple then helped each other get back on their feet and left.
