In 1906, Nguyễn started working at the French Viễn Đông Bác Cổ in Hanoi.[1] In 1913, he joined the editorial board of the Đông Dương tạp chí — a magazine that actively promoted Quốc ngữ via translated articles from original Chinese and French works, managed by Nguyễn Văn Vĩnh.[4]
Nguyễn was appointed chief editor of Trí Tri magazine in 1921, then chairman of hội Trí Tri (an educational movement for promoting the French language) in 1934.[1]
In 1938, Nguyễn Văn Tố together with Bùi Kỷ [vi], Tôn Thất Bình and other associates with support of Nguyễn Văn Huyên, Trần Trọng Kim, Hoàng Xuân Hãn, Lê Thước [vi] formed Hội Truyền bá học chữ Quốc ngữ (en: Association for the diffusion of Quốc ngữ, fr: Association pour la diffusion du Quốc ngữ) to eradicate illiteracy via popular libraries and free Quốc ngữ courses.[5]
From 1941 to 1945, Nguyễn wrote hundreds of articles about Vietnamese culture and Eastern culture for Tri Tân magazine [vi][3]
Nguyễn Văn Tố authored many works under his pen name of Ứng Hoè, but one of his works under his real name was a list of Cham place names that existed or still exist in regions of Central Vietnam once occupied by people of Champa.[6] Most of these villages no longer exist.[citation needed]
