The footage shows five men watching her dangle from the window, from the street below, before dashing to the correct spot to catch the girl named Qiqi.
The state television quoted her parents as saying that they had left Qiqi home alone while she was sleeping, but that she had climbed onto the windowsill after she woke up.
Upon hearing the girl's cries, workers from the neighbour delivery company came out onto the street and saw her dangling from the window.
After shouting to reassure the girl, they managed to break her fall with their outstretched arms as she plunged to the ground.
Two men were injured in the rescue, one hurt his neck, and the other one hurt his arm.
Qiqi herself escaped with just a graze on her face.
