Where the China Mass Spectrometry Society (CMSS) was founded: The CMSS (http://www.cmss.org.cn/) was established on September 22, 1980, in Hangzhou, Zhejiang Province, providing a rich historical context and academic environment for hosting the International Mass Spectrometry Conference in Hangzhou. The inaugural meeting, held as the Mass Spectrometry Branch of the Chinese Physical Society, saw participation from 136 institutions and 147 representa-tives. The conference adopted the "Charter of the Mass Spectrometry Branch of the Chinese Physical Society" and elected its first council, with Qinglian Zhang being named the inaugural president of the society. This marked the beginning of a new historical era for mass spectrometry development in China. The society conducts a general assembly every four years, a national aca-demic exchange conference every two years, and annual meetings of various professional committees in odd-numbered years. In response to recent advancements in mass spectrometry and the expan-sion of interdisciplinary fields, the coun-cil has restructured the society into five specialized committees: Inorganic Mass Spectrometry, Organic Mass Spectrom-etry, Biomedical Mass Spectrometry, Isotope Mass Spectrometry, and Mass Spectrometry Instruments and Educa-tion.
