No, that was Tae soo do by the way. I was not saying Tang soo do was part of Taekwondo, the original plan of Choi, and the Korean government was to unite all Korean martial arts under the banner name Tae kwon do. This was unrealistic, and in the end did not turn out that way. Tang soo do was never a part of Taekwondo, but it like many other Korean martial arts at that time was going to be called Taekwondo. Many opposed this, and it never really happened.
