The reputation of Qigong was destroyed by the Qigong craze in the 1980s. At that time, everyone dared to call themselves qigong masters. In fact, many so-called qigong is actually a slow-paced square dance, which wastes time. The wheel got up at that time, and then someone took the opportunity to speculate that "practicing Qigong can develop super powers" (some cities where this fake Qigong is popular are about to be blown into academic parks). Influenced by these monsters, many people now think that Qigong is fake. But I have to say that this is actually true, but it is far from the fantasy described in the martial arts novels. When the real qigong is running, you will only feel that there is an "energy" running in your body, and your consciousness will enter a state of half dream and half waking. To a certain extent, your senses will become more acute, but it needs to be practiced with martial arts, otherwise you won't care even if you notice some small moves that you haven't noticed before. This is my personal experience.
People who say that Qigong is pseudoscience are superstitious about pseudoscience themselves. Just because you don't understand doesn't mean it doesn't exist. Gravitational waves are beyond ordinary people's understanding, but can we say that they don't exist? He also said that the qigong master was beaten. Can you trouble those guys to aim at the toilet before farting, so as not to collapse in the wrong place? Qigong is not to strengthen the fighting ability, and the increase of physical strength is only an additional effect. Those so-called broken stones in the chest or broken legs are either fake qigong or fast-paced hard qigong (in fact, the so-called hard qigong belongs to external work and must be combined with fighting skills to play its role). The real internal strength (narrow sense qigong) is health preservation. This kind of thing will not be handed down for decades. I suggest you meditate. This is an introduction to Qigong, which is relatively simple.
