It's not that easy. . . See how you practice. If you want to have a sense of qi, of course, you must do internal work and guide qi with your mind. If you only take doing exercises as a form of practice, you won't feel angry even after practicing for several years, but you must have the guidance of a master if you want to improve your internal skills. If you are strict and meticulous, you can feel the qi in three months, but it is normal that the qi is flickering, erratic and unstable at this time. Stick to it, it will enrich your internal qi. Generally speaking, people who are angry are more interested in learning boxing. So the process of enriching yourself from anger is generally no problem. The difficulty lies in the process from scratch. Many people can't stand being bored. A good master will take you to learn a unique skill for a week or even ten days. He asks you to behave yourself in every move. Many people can't stand that temper and always want to learn quickly. As a result, the foundation was not firmly laid.
