Yes they also learn stuff like jijitsu or kung-fu
The art of Tae Kwon Do is probably very original from Korea and could be as old as Korea itself! I would say the closest martial art would be Hap Ki Do, which is also from Korea, and also as old as the first one. Even though these two martial arts are very different, the do share some of the basic moves, such as certain kicks and punches. I'm no historian, but did have the privilege of practicing both sports. Hap Ki Do as a small kid, and Tae Kwon Do as a teen. In my opinion, Hap Ki Do is focused more on the self defense side, and Tae Kwon Do is more on the aggressive side. I would even compare Hap Ki Do to Judo and Tae Kwon Do to Karate if I had to make an analogy.
