This is the moment a young girl saved her little sister from choking on a sweet - using the Heimlich maneuver.

Doudou, six, and her younger sister Woniu, three, were spending an evening at home in Hainan Province, China, when Woniu started choking.

Video captured in August shows Woniu rushing into the living room to find Doudou and show her that she had something stuck in her throat.

Doudou immediately jumped into action, stood up and started performing the Heimlich maneuver on her littler sister.

Doudou had seen her mother perform the Heimlich before on Woniu, which is how she knew how to act so quickly.
