There is a growing interest in EM/CA in China, and I’m delighted that Enhua Guo, from the Ocean University of China, has written us a lively and informative account of new developments. In celebrating the 100^th HDS (“Happy Data Session”) in China, he reflects on its evolution over the past three years, highlighting local practices, and sharing key takeaways with the international EMCA (Ethnomethodology and Conversation Analysis) community.

Data sessions are a crucial component of EMCA research and serve as one of the most fundamental means of conducting EMCA studies. On the foundational and pioneering work done by K.K. Luke (陆镜光), EMCA in China in the past two decades has seen remarkable development and growth, thanks to the unwavering efforts of some leading Chinese conversation analysts as Guodong Yu (于国栋), Yaxin Wu (吴亚欣), Wei Zhang (张惟), along with Ni-Eng Lim (林尔嵘) from Singapore.

CA is well established in a number of Spanish-speaking countries, but there is always room for more initiatives, and for ways for sometimes isolated researchers to meet together. I’m delighted that Luis Manuel Olguín has sent in a report on the Seminario Permanente de Análisis de la Conversación, a lively and inclusive forum for Spanish-speaking CA researchers.

Although CA is well-known across Spanish-speaking academia, resources for learning and teaching CA in Spanish are still significantly scant, especially if compared to other approaches to language use and social interaction with established traditions in Spain and Latin America. Similarly, the Spanish-speaking CA community is still relatively small and largely scattered across countries, making it difficult for CA to take root in Language and Social Science programs and departments.
