The EFEO printed this list as a leaflet which was entrusted to civil servants of the colonial administration (Questionnaire linguistique, Hanoi: Imprimerie d'Extrême-Orient, 1938), aiming at extensive coverage of language varieties. The investigation was launched in 1938. Filled leaflets were gradually gathered at EFEO in Hanoi, until the process was interrupted by the war (in 1940).
