It's normal for martial artists to kick people. Usually after three to five years of special training, he will have this skill. How far he can fly depends on his skill. I have seen a person who can kick a person over 1 m, that is to say, the whole person moves over 1 m in the air, but the master usually doesn't practice kicking for many meters, mainly because of the instantaneous impact and penetration. A person who can kick a person above 1 m may not be able to kick a stake in an instant, but a master can kick a stake in an instant. Such people are hard to find now.
There is no real video of Bruce Lee practicing martial arts. His wife recorded a little video at that time, but it was incomplete and only fragments. There used to be a video of Bruce Lee practicing martial arts on the Internet, but it was later found that he pieced together his scenes in different movies.
