How to grasp the backhand of table tennis and rub the right-handed ball

Generally speaking, from one's own point of view, the ball rotates from one's right side to the left like the left side, and vice versa;

Generally, there is no pure side spin ball, usually side topspin or side backspin.

The opponent sends the ball to your backhand position and the ball spins to the right. If the shape is not adjusted, it will be placed vertically. Because the ball is rubbed, it will naturally lean to your left after hitting your racket, or even fly out of bounds, so your board should be tilted to your opponent's left hand side.

Distinguish between side topspin and side backspin. If it is a side spin or a pure side spin, never rub it, but push or dial it. If it's a side spin, wipe the opponent's left hand side.
