China National Committee for Terms in Sciences and Technologies (CNCTST) is a top management agency in China. It was established in 1985, aiming to introduce new terminology, endorse changes of borrowed terminology, alter the standards of terminology, explain unfamiliar terminology, and adopt practice to make terminology more accurate. CNCTST tries to standardize terminology practices in the country. Under the management of CNCTST, a considerable number of terminology databases have been constructed to serve the academic research and practical translation. Furthermore, CNCTST officially launched the first phase of DISE (data intelligent search engine) platform named TERMONLINE on June 15, 2016, and launched the revised second phase of TERMONLINE on September 17, 2020. This article will discuss both different periods of CNCTST and its successful management in Chinese terminology research and practices.
