To clarify,
I told about my back pain,
So I did some twist the sport of the waist.

in China,
twist the sport of the waist is the standard posture for fitness exercises.
It is also a posture for rehabilitation exercise.

I mentioned in the text,
I have backache ,
So I did this twist the sport of the waist,
I also mentioned,
To accelerate recovery my body,
I also used this health patches.

So I mentioned 2 things,
Do sport and use health patches.

is not only introducing that product.

That product and "twist the sport of the waist" ,
Can help each other,
Can help the body recover.
So I mentioned them at the same time.

If you think I am introducing that product,
it is also related to sports!

It's like professional baseball / professional basketball / professional basketball / etc.
These are the products,
Is a sporting product,
Can't those sports be commercialized?
Isn't commercialization a movement?

Professional athletes can earn hundreds of millions of dollars a year.
Although those sports have been commercialized,
They also make high income,
But they still think they are sporting,
So calling himself an athlete,
is not calling himself an laborer.
