How can I fold the dirty clothes basket back?

1. Grasp the two diagonals with two hands, and then merge them together. If the two corners below are not merged, touch them with your hands. At this time, the cuboid becomes a rectangle.
2. Hold the dirty clothes basket with both hands flat, and look at yourself.
3. Hold the dirty clothes basket tightly with your left hand, and don't move. Twist your right hand hard into your arms, and then insert the circle in your right hand into the circle in your left hand, and then press it down.
