French Missionary Dallet (1874) introduced ‘the thousand character essay’ to the western world. The thousand character essay is called as ‘Tcheonzamun (千字文)’ in Korea. There are two methods for translating Tcheonzamun poem. One is through Korean pronunciation of Chinese character (Park et al., 2021 b). The other is through the meaning of Chinese character on Tcheonzamun (Park et al., 2021 a). In the present study of the Tcheonzamun translation, the second method (Park et al., 2021 a) was utilized. And the range of this study is 16 letters of Chinese characters on Tcheonzamun (Tcheonzamun 817th-832nd). The title of this work is ‘My Lord! When is it possible for me to become mature? (Tcheonzamun 817th-832nd)’. The theme of this research is as follows. 821-824 老(No) 少(Syo) 異(Ih) 糧(Nyang). Suggesting that there is a silly (少) man, and he is not mature. He wants to live freely upon his own intention. In order for the man to be mature (老), what will he do? My husband! If you get to know the fact that everyone is not same. If you come to know that each (糧) person is different (異). At that time, you will be mature!
