The method of making an origami boat is as follows:

1. Place the square paper horizontally, face down. Fold it in half from bottom to top and open it to form a horizontal fold line.

2. Fold the upper and lower sides inward to align with the horizontal midline.

3. Turn the paper over, and fold the upper and lower sides inward again to align with the horizontal center line.

4. Turn the paper over again, and then fold the two corners of one end inward until the edge is aligned with the horizontal center line, as shown in the picture.

5. Then fold the two corners of one end inward until the edge is aligned with the horizontal centerline, as shown in the picture.

6. Use the same method to fold the other end into a sharp angle.

7. Now open one end, pull up the folded corner (pointed by the red line), and tuck it into the bottom layer (pointed by the black line).

8. Fold this side again.

9. Fold the four corners at both ends according to steps 7 and 8.

10. Turn the paper over again and open both sides of the horizontal center line.

11. Finally, arrange it into the shape of a small sampan.

Relevant knowledge:

1. A sampan is a simple small vessel with a wooden or iron hull. It has the advantages of easy use, flexible operation, and convenient manufacturing. It is available in almost every household in the coastal breeding industry. The power source is usually oars on the left and right sides or a bamboo pole, but a few use motors.

2. The safety factor of this kind of boat is low. Many places have banned small sampan boats from fishing and carrying passengers. Even so, many people still choose this type of ship because of its two advantages: first, the structure is small, simple and light, suitable for operations in smaller waters, and it is economical and cost-effective. The water in these working areas is often very shallow, and there are no undercurrents or whirlpools. Even if you accidentally fall, it will not be a serious problem.
