Don't think too much about qigong. It's just a fitness method. No matter how profound and complicated it is, it can't be practiced. You must start first. As an exercise method, Qigong mostly has its own specific methods, such as endless Gong Zhuang, Baduanjin, Taiji, Yijinjing and so on. This is a way to achieve physical and mental health through breathing and breathing in a specific posture. In fact, it is a way to achieve perseverance, perseverance and understanding through contact. For example, practice nature: the so-called nature is to follow the trend, so don't say nothing in the morning and still play. If it is windy and rainy, you still have to practice outside, that is, there is something wrong with your head, so you should pay attention to practicing step by step. Starting from what you can accept, the time posture will increase little by little.
There is also a method obtained by practicing martial arts and applied to doing things. For example, Taijiquan pays attention to roundness, gaining momentum and borrowing momentum. Personally, I suggest practicing Yijinjing. There is a teaching version online, which is relatively soft. Who do you think is suitable for practicing what moves? If you want to practice deeply, you can worship a master, but it's hard to say whether people accept it or not.
