Do Japanese "ninjas" really have flying skills? You can fly to the roof. Is there really lightness skill in the world?

I think China has a light achievement. Just lost.

My grandfather's father is a kungfu practitioner. A wall 2 meters high can jump at once. Of course, I didn't see these with my own eyes.

According to my family, practicing martial arts is very difficult. The first thing to do is to "pinch the bones", that is, to spread the bones, meat and tendons. This requires a long-term push and pinch. If the pusher is a little careless, or the child is too weak, it will ruin the child's life. My grandfather was an only child, so he didn't inherit it.

On the whole, I believe in something close to magic like this. China's ancient culture was great, but those masters never wrote books, and their superb skills were passed down from mouth to mouth, so they were easily lost. For example, people nowadays can't restore Yuanmingyuan, because the technical content inside is too high for modern people to master.

Of course, there is a limit to kung fu. I don't believe it's like in TV series.
