Korean terminology in many Taekwondo schools plays an integral part in martial training. Tan'Gun Taekwondo is no exception. First & foremost, students are expected to know their basic counting (1-10). From that as a natural process of development should come the understanding of differing techniques through the terminology. Here is the information every student will need to count to 100 should they wish.

Korea has two counting systems. One is of Chinese origin and the other is the Korean system. Korean numbers only go up to 99 and are used to count days, minutes and mileage (as long as the total doesn't exceed 99). The Chinese system is used to count money, because the smallest Korean banknote is W1000 (South Korean Won).

When the Koreans borrowed the Chinese counting system, they also borrowed the 'unlucky' number four. It's unlucky because it also sounds like the Korean word for death (sa), unfortunately another word which was borrowed from the Chinese. If you have any Korean friends come to visit you in your own country, it's probably a good idea not to check them into a 4th floor hotel room. Not actually a problem in Korea itself as hotels don't have a 4th floor and hospitals never do.
