Yes, because Koreans have been using Chinese surnames and names for a long time, but some people still pass down their real names.
Korean names written in Korean can only represent the pronunciation, which makes it easier to have duplicate names. Therefore, in some more formal occasions, Chinese names are still more common.
So everyone must have a Chinese character name. The name must have Chinese characters when registering the household registration. The corresponding Chinese character name will also appear on the ID card. If there is no Chinese character name, the household registration officer will find a way to give it. You make up a Chinese character name, so every Korean name has a corresponding Chinese character name.
Korean characters come from China, but the fonts of Korean characters are taken from the way of heaven, earth and people, as well as the way the letters are written. They actually imitate the tension of human pronunciation organs, rather than completely coming from Chinese in form. , it cannot be separated from Chinese characters, and it is completely derived from some radicals of Chinese characters, so the proportion of Korean derived from radicals is not large.
