Compared with modern Chinese, the inquiry sentences of the unearthed Warring States documents occupied an important position in oral communication at that time, and their expression methods were quite distinctive. Through exhaustive corpus investigation and systematic description, four types of inquiry sentences in the excavated Warring States literature, such as specific finger questions, right and wrong questions, positive and negative questions, and choice questions, are discussed, and the special questions used in them are discussed, and the grammar of the special question sentences used in them is explained and analyzed. The study found that the interrogative sentences in the form of questions and answers in the excavated documents mainly include two types: Chujian quotation style corpus and Qinjian Zhongluling corpus. Finally, the different distribution characteristics and regional relationships of the interrogative sentences in the Chujian and Qinjian corpuses were answered.
