Korean is the official language of South Korea, but it is called Korean in North Korea. They are different dialects of the same language.

After World War II, due to the nationalism of the Korean nation, South Korea and North Korea have completely abolished the use of Chinese characters, and all of them are written in proverbs (Korean characters).

When Korean characters are grouped, syllables are used as a unit, and one syllable constitutes a Korean character. The arrangement of each letter follows the two basic rules of "from left to right and from top to bottom". The syllables in Korean are composed of initial consonants, middle vowels and final consonants. In the practical application of language, some syllables have three parts; Some syllables have only initial consonants and vowels, but no final consonants; While some syllables have vowels and final consonants without initial consonants; What's more, there are only vowels.
