Coach Meng teaches the "breaking" backhand ("Kaitai", "Kaidai" or "haru", according to the English subtitles) used often by Lin Gaoyuan, and compares it to the more powerful but difficult to master Kō (or "Kong") technique (Harimoto style). Breaking is something like an active block, with elbow stable and rotation of the forearm to the right (for right handers) on contact to add spin. Kō involves punching forward with elbow extension and whipping through with rotary motion on contact to add spin.
