Originated in china with a long his-tory,"shuji"is the most important word for record-ing time,words and events in the early history of mankind.Both the skills of"shuji"and the tools of"shuji"fall within the scope of the history of technology.The historical evolution is briefly illus-trated as follows:in the ancient times,the"mul-berry tree"was used as a tool,and the time,words and deeds,etc.were recorded first with"shu"and then"ji"—in the Qin and Han Dynasties,the records accumulated into the national"book archives"—in the Qin and Han Dynasties,it meant skills and techniques—in the Wei and Jin Dynasties,it developed into a literary genre—in the northern and Southern Dynasties,it gradually became an"official document"—after the Tang Dynasty,the official name"Zhangshuji"appeared.In modern times,"shuji"as an important symbol of the history of civilization and technology has died out.The reason is that the Russian word CekpeTapb which means the official title"secre-tary"was translated and introduced by Russia from"shuji",and that led to confusion with the an-cient Chinese"secretary(shuji)".In fact,the two are not cognate words.
