Xiao Zhang played a very important role in the establishment and development of ancient Chinese. In the mid-1950s, Mr. Zhang Xiao of Beijing Normal University and his Chinese Department first proposed to the national education department to offer ancient Chinese courses in the Chinese Department of colleges and universities. During his 30 years as the leader of the Chinese Department, he personally formulated the syllabus and curriculum plan, and put forward the teaching system of the Chinese Department of Normal University with modern Chinese, ancient Chinese, modern literature and ancient literature as the four pillars, which won the reputation of the Chinese Department of Beijing Normal University among similar universities in China. In the early 1960s, Mr. Zhang Xiao participated in the compilation of the textbook Ancient Chinese edited by Mr. Wang Li, and served as the person in charge of the collection.
Mr. Xiao's research direction focuses on writing and exegetics, highlighting the inheritance, summary and development of traditional exegetics. The collection of essays, textual research and exegesis, and Shi Mao's monographs, which he personally selected and compiled, reflect his spirit and methods of doing scholarly research and are precious wealth left to us. Xiao Zhang has made great contributions to the inheritance and development of traditional linguistics in China.
