Because there must be professionals in the general non-professional group, the so-called professional, provincial and municipal teams are not counted first, that is, there are some people who have practiced in the Daoguan since childhood, and it is impossible to accurately distinguish them, because competitive competitions, training time and location can not explain the problem, so the general result is this: professional competitions and non-professional competitions are actually similar in top level and similar in bottom level, that is, there are generally some differences.
If a league match is divided into professional and non-professional groups, it will be a little different.
In addition, I told my friends above that many Dojo will invite many experts, not even Taekwondo practitioners, to participate in various leagues and amateur competitions in order to build their brands.
The national college league you mentioned is generally better, but because it is not a regular league, it can not get extra points like primary and secondary school competitions. It's just an experience of your training results. You should sign up and feel more.
