The apparently random sequence in which countries marched out at the opening ceremony of the Winter Olympics had many observers scratching their heads, but it was indeed in alphabetical order -- in Korean. Greece emerged first into the arena on a sub-zero Friday night, in line with tradition because that is where the Games originated from. But next to march, to much bewilderment among non-Koreans, was the skeleton athlete Akwasi Frimpong, the flag bearer for Ghana. Compounding the confusion for many, Ghana were followed by Nigeria, South Africa and then the Netherlands. Organisers clarified that none of this had been a mistake and the order was based on the Korean alphabet, Hangul, which was developed in the 15th century to replace Chinese characters.
