The girl, Qiqi, escaped with small scrapes on her face.
The security camera footage aired by CCTV showed a group of men in an alley pointing and looking up the side of a building. They dash into a huddle just as the youngster falls into their arms.
CCTV said workers at a delivery company nearby heard the girl crying as her legs dangled out the window. The report quoted her parents as saying they left Qiqi home alone while she was sleeping but she climbed onto the windowsill after she woke.
It happened Thursday in Ninghai, in eastern Zhejiang province.
