2. Slide the space beans into the fishing line.
3. Tie a figure-eight knot under the space bean and tie the figure-eight tightly.
4. Tie an 8-shaped knot above the space bean.
5. The two 8-shaped knots play the role of fixing the space bean, so that the space bean does not draw the range of the two 8-shaped knots. At the same time, there is a coil between the two 8-shaped knots to connect the main line and the fishing rod.
