It is never too late to be 30. In history, some people didn't meet Master until they were 70 or 80 years old, and finally got it. So what have you been doing for 70 or 80 years, in fact, you have been undergoing the tempering of life. When you hone to a certain degree and your personality has changed greatly, you can really learn advanced Qigong. From this perspective, thirty years old is not too late.
If you want to find a nearby master to teach you Tai Ji Chuan or Qigong, you can only pay attention to it yourself.
But let's go online and read some information first. In this era, the Internet is really a good thing, and there is everything on the Internet. Of course it's true or false. You have to identify it yourself.
China Qigong (not called Qigong in ancient times) has a principle of "taking morality as the foundation". First of all, we should be patriotic, respect our predecessors, take things by surprise, and take the masses as our parents. If you can find such qigong materials, it won't lead you astray. I suggest you look at these materials and practice some skills.
But you may prefer to learn from the teacher, so you'd better find it nearby. However, the problem of master is closely related to fate, and the concept of "master" is the key to practice. There is a difference between a famous teacher and a wise teacher, not to mention the difference between a real teacher and a fake teacher. It is usually not easy to find a real master. You must rely on your virtue to find such an advanced master.
Of course, everyone's fate is different and the foundation is different. If you have Chen Taiji's teacher there, or other teachers of Neijia Boxing, you can worship them as teachers and learn Neijia Boxing. Maybe you are more interested in this now.
It's not too late to be 30, even if you practice the well-known family boxing in society. For example, Mr. Ma Hong, one of the disciples of Chen Zhaokui, a direct descendant of Chen Taiji Biography, began to contact Chen Taiji Biography when he was in his forties and sickly. A few years later, he learned a lot of problems and later became a famous boxer.
