Let me explain, don't ask if you can grow taller, just stick to the horizontal bar and see the effect.
Of course, it needs long-term persistence. Don't give up until you see much effect. A ray of light is hope.
The key to hanging the law is to look at yourself. Hang up once and stick to the limit. The grouping is also arranged by yourself, depending on your time and physical strength.
There is no horizontal bar, as long as it is the kind of hanging body, such as doorframes, ladders, a series of things that can be hung by themselves!
Generally speaking, it is hung for a year every day, at least 3-4 cm.
