Hanryu and Bikkak are the names of two forms that are believed to have been candidates to become new Kukkiwon/WTF-style poomsae somewhere in the ~2007 timeframe. The idea was that these would be forms that could be used in competition. The forms did not become a formal part of the Kukkiwon curriculum however. * Hanryu was intended to be a competition form for older competitors (over age 40) * Bikkak was intended to be a competition form for younger competitors (under age 40)
