At last, the in-depth original meaning of Lao Zi in the Dao De Jing scripture is being studied and translated into English. A number of terminologies used in the original text in Chinese had been analysed, explained and translated into English. Some terms in Chinese without the parallel meaning in English were fully explained and Hanyu Pinyin was used. Examples are 'yin', 'yang', 'hun', 'po', 'jing', 'qi', 'shen' and 'wu-wei'. Lao Zi was the first "Prophet" to explain "Dao" and "Dao cultivation", including nurturing one's moral virtue. Also, the philosophy of governance and military philosophy were also fully explained.
