How to use this expansion screw? Little sister won't? Thank you all. Hang a picture.

Use 6# impact drill to make a hole 4~5cm deep in the wall. First, knock the white expanded plastic sleeve into the hole on the wall, flush with the hole, then screw the screw into the expanded plastic sleeve on the wall with a screwdriver (leave a position of 3 mm), and then hang the hook on the picture frame on the screw.
