1. Prepare five lines for alignment, and tie a two-way flat knot about 2cm in the middle of these five lines with another line. 2. Fold the flat pair, and then continue to make a set of flat knots with all lines as the axis. When finished, cut off the two wires and burn them, and tighten all the wires on the back. 3. Take a thread on the left and right, and hang a bird's head on the other thread.

5. Take a thread from the right side of the core thread in the middle, wrap all the other cores and tie a half-bird's-head knot. 6. Don't knit the first thread added on the right. Take the second thread as the axis, the third thread as the winding, the fourth thread as the axis and the fifth thread as the winding, and make a set of oblique knots. Finally, conversely, make a set of oblique knots with the seventh thread as the axis and the sixth thread as the winding.

7. Take the line knotted by the bird's head in step 5 as the axis, and weave all the lines (including the first line, a total of 7 lines) in step 6 into a row of oblique knots. 8. The same is true for the left side, and the axis is taken from the center centerline. 9. Repeat step 5. 10, repeat the sixth step, but the first line should also be 1 1, and the left and right sides should do the same. 12, the fifth step of the root is a little different here. The first thread on the right is wrapped around the first thread on the left and the core in the middle, making a semi-sparrow head knot.

13. Here, as in step 10, the first line should be compiled (the first line should be compiled layer by layer from the beginning without repetition), and the two lines marked with X at the end should not be compiled (it has not been compiled since). 14, same as above, until the last two lines are left. 15, don't worry about other lines, just tie an anti-skew knot and tighten the last two shafts. 16, cut off all the extra lines and burn them.
