The Inter-regional Forum on Chinese Dialectal Grammar (IRF) was initiated by The Chinese University of Hong Kong and Sun Yat-sen University in 2015 and this partnership was extended to Fudan University in 2017. The forum has since become an academic event organized rotationally by these three institutions as a platform to foster research on dialectal grammar under a comparative approach focusing on southeastern Chinese dialects like the Yue and Wu dialects, to promote inter-regional studies, and to further intellectual exchange and dialogue among researchers from different regions.

The Fourth Inter-regional Forum on Dialectal Grammar, organized by the T. T. Ng Chinese Language Research Centre, was held on 15–16 June 2018. For the details of the forum, please visit http://www.cuhk.edu.hk/ics/clrc/irf/
