He set up the Cam Cultural Centre to study the Cam language and to form a team of researchers with the cooperation of old Cam scholars. They collected ancient texts, translated them and published them. A Cam-Vietnamese-French dictionary was issued in 1971. Two thirds of this population "follow a religion which was no doubt Brahmanism in the past but it is now only a distant souvenir of the religion coming from India". The last third are the so-called Banis who are descendants of Cam families who have opted for Islam since 14th or 15th century. These two communities have their villages, theirs clergies, their own rites. They don’t get married between them but keeping their relationship (same Cam calendar and some formal occasions). A small part of this ethnic group establishes in southwestern Viet Nam not far from the border of Cambodia. In this country however were living the majority of Cam people. That was what pointed out Gérard Moussay when he had arrived into Phan Rang.
