Why the Kukkiwon replaced Palgwe poomsae by Yugupja Taegeuk Poomsae





Palgwe Il Jang is one the poomsaes that only the old Taekwondo generation know, and if you ask students who started Taekwondo in this century about them you would notice that they have no idea about the name, except is there are grand masters or masters mentioning them or sometimes teaching them. 
Palgwe 1 poomsae are different than Taegeug 1 poomsae. 
Example of differences :

The stances in Palgwe 1 are Ap Kubi (front stance) and Dwit Kubi (back stance). 




The stances in Taegeuk 1 are Ap seogi (walking stance) and Ap kubi (front Stance).
