Abstract: This paper points out that the Chinese sentence "他打得孩子到处乱跑"(meaning "He beats the child to run about everywhere") should not been considered as a jianyu sentence,on the other hand,we should treat this structure as complement behind "de".This paper discusses this according to the origin of "de"-verb-complement structure,the treatment of the part behind "de" in current Chinese and the mistreatment of the sentence by SUN Yinxin.
