Original title: Full screen knowledge points! All focus and walk, no one dares to rub the ball in front of you! -Ping Pong National Golf Club
Guoqiuhuijun likes to watch the questions raised by the golfers very much, and can always learn a lot of things, and once again recognize his own shortcomings...
As soon as he received this question, Jun gave up: then stop pulling it, isn't it good to rub it? . .
收到这个问题后，Jun放弃了：然后停止拉动它，摩擦它不是很好吗？ 。 。
It seems that you have the potential of iron rubbing~ Can't come with comprehensive technology, can only take advantage of outstanding specialties, curve to save the country!
Professional coaches are definitely different. They can answer everything. Is the answer in place? @马群 The first step:
The ball that rotates particularly does not move forward, and falls down after falling; for the ball that does not rotate very much, it rushes forward.
If it is judged to be particularly spinning, pull the middle and lower part of the ball and rub it upwards to exert force without impact.
