Zheng Su Wen is an important colloquial dictionary written by Hao Yixing in the Qing Dynasty. It is the part of foreign words in the last two volumes that specially makes significantly differences from other dictionaries which also specialized in collecting common words. At present, its value has been found, but comprehensive description and investigation are still rare. Therefore, this paper makes a detailed survey of the two volumes of collected words and described them from the basic situation, regional distribution, vocabulary source and historical stages. And it also observes Hao’s interpretation, citation and textual research of foreign words, so as to summarize their characteristics which are as follows: firstly, these foreign words are influenced by regions and Buddhist culture; secondly, bibliography of these words covers a wide range of both Chinese history and domestic and foreign regions; thirdly, Kangxi Dictionary may closely be related to them. Lastly, this paper divides words into two categories according to whether the dictionary and other dictionaries are included as a judgment standard. Some words should be emphasized in the future, while some words should also be supplemented and demonstrated.
