1. Fold a small note at the bottom of the paper, and fold the same note at the side after folding.

2. After folding, fold the paper in half, face down, then spread out the small strip part and evenly spread the glue stick, just like video operation.

3. After gluing, fold it in half again and open it. Choose two corners and fold them into a small triangle, then fold them in half.

4. Then unfold the paper, select the corners on both sides to fold inward into a big triangle, and unfold it as in the video.

5. Then open the paper from the gaps on both sides of the paper, so that the paper becomes a hollow rectangle.
