How to draw Chinese knots with axisymmetric figures

Chinese knots are axisymmetric figures. As long as any set of corresponding points is found, the verticality of the line segment connected by the corresponding points is made. According to relevant information: we draw a trapezoid, but the difference is that the upper end is an upward curved arc and the lower end is an ellipse. Then we draw a rectangle decoration in this trapezoidal pattern, and then draw an arc under it as decoration. Then we draw a small arch bridge-like figure on the top arc, three on the left and right, leaving a gap in the middle, and then draw a blank on the top of the trapezoidal arc. At the same time, we can also write a spring or blessing in the blank, and then paint it red, which is more perfect.
