Duan, Yu-cai has commented, ”there are single-part pictographs, and conjoin parts, too”, and ”the Conjoins are based on which parts and images derived from its form.” However, there is something to discuss. deeply in Duan's words generally. This paper discusses the 157 characters, which are ”based on which parts, pictographs” in Sou-wen2-jie3-zi4, referenced with 11 philologists' pieces in Ching Dynasty. I discuss the forms of these 157 characters, and divide into two parts, the main parts (Main) and the subordinate part (Sub) . After researching the conjoin styles of Main and Sub, I deduce them into 13 categories. Then discussing their integrations, relations representatively, and their phonological rules regarding as well, I conclude some revises and supplements about the Duan's words, and also I thought serve these findings as an future researches reference for philological academic field.
