For example, the foot Sanli is in the position of four transverse fingers below the lateral knee eye, and can be massaged with the hands. First feel the lateral knee eye, massage the depression below the lateral knee joint, and you can apply pressure on the area where there is soreness and swelling, which is the location of the Foot Sanli.
