Wu Juping is just a saleswoman. However, on July 2, 2011, she bravely caught a falling child and has been praised as the most beautiful mother in China. The child fell from the 10th floor of a building into Wu’s arms.

The child is two years old, who named Niu Niu. Niu Niu climbed up to the window looking for her grandma. When a neighbor living one floor saw the little girl falling, he held out a ladder(梯子) to catch her. The ladder, however, was too short to reach the girl. At this dangerous moment, Wu, who was just walking near the building, rushed to the spot and caught her successfully before she hit the ground.

The girl fell into coma(昏迷), and Wu was also injured seriously in her left arm. On July8, Niu Niu, who was able to move her fingers, feet and eyes, was out of dangerous condition and Wu’s arm is recovering well now.
