宋宗宇

Song Zongyu is a Chinese author whose writing centers on construction engineering law. Public information about him is limited, and his biography, nationality, and educational background cannot be confirmed. Judging from the three works held in the collection, he has consistently addressed the subject of construction engineering regulations, including Introduction to Construction Engineering Regulations, its fourth edition, and Construction Engineering Regulations (3rd Edition). The repeated revisions of the introductory volume suggest that the topic meets a certain demand in teaching and professional practice. His works fall under categories such as law, architecture, and examinations, focusing on organizing regulatory provisions and their application in engineering practice, with a textbook-style, systematic approach suitable for students and practitioners in related fields.
