There is a person who always wins me in table tennis, but always loses others, I always win others always lose him, how is it?

Everyone has their own way of playing and their own way of dealing with it.

Some people are adapted to straight cross-court play and are good at defending against straight cross-court play, but when it comes to chipping, they can't do much about it.

On the contrary, some people specialize in chipping. It depends on whether they are familiar with each other's routines and whether they have a way to break them.

This is what is known as a match.

So what you're seeing is normal. Take your time to study your opponent's style of play, practice in a targeted manner, and I believe you can win back.

I hope this helps.
