The purpose of this study is to clarify the characteristics of modern vocabulary and grammar through the study of Diachronic evolution. The author investigated the diachronic evolution of the verbs of “go to+L”. The verbs of “go to+L” are “如(ru)”, “适(shi)”, “之(zhi)”, “往(wang)”, “去(qu)”. All of verb was existed in ancient time. “往(wang)” was the main used in ancient time. “去(qu)” took over “往(wang)” from Yuan Dynasty up to now. Since MingQing Dynasty, “往(wang)” had begun to grammaticalization of Verb into preposition or a complement. The author also investigated the reason that “去(qu)” is transitive verb and the cause of the difference between “往(wang)” and “向(xiang)” in modern Chinese. The reason that “去” has the characteristic of transitive verb is because that Although meaning of “departing from” in “去(qu)” changed to “go to+L”, but the structure of “去(qu)+L” has been maintained unchanged and succeeded to modern times. In addition, the reason why the object behind “往 (wang)” is specific place noun or Noun of locality is because that it have preserved the characteristics of Verb.
