In Korea, it is not easy to see Chinese character in the street. But contrarily in Japan and in China it is dfficult to find out letter without Chinese characters. The reason of this little use of Chinese character in Republic of Korea might be the existence of Korean letter, Hangul. But the present researchers consider if there is another reason for this different phenomenum in these three Eastern Asian countries. The researchers, we, translated the Chinese characters from 0106 to 0115, and we found some results. For example, 1) Tcheon(天) = Il (一) dae, tae, da(大) →Itta!; 있다! (There is!) 2) Za(字) = Za(子) myeon(宀) = Za myeon; 자면 (If you take a rest.) 3) Ga (家) = Si (豕) myeon (宀) → Swi myeon; 쉬면 (If we can take a rest there, it is the home). The hypothesis is as follows; a) Koreans have created Chinese characters, and after a long time Koreans created again the Korean alphabet (Hangul). b) On using Hangul (Korean alphabet), Koreans do not have any great incovenience without Chinese characters.
