Previously, it was believed that Thành (Ho) was involved in an anti-slavery (anti-"corvée") demonstration of poor peasants in Huế in May 1908, which endangered his student status at "Collège Quốc học". However, a document from the Centre des archives d'Outre-mer in France shows that he was admitted to "Collège Quốc học" on 8 August 1908, which was several months after the anti-"corvée" demonstration (9–13 April 1908). The exaggeration of revolutionary credentials was common among Vietnamese Communist leaders, as shown in North Vietnamese President Tôn Đức Thắng's falsified participation in the 1919 Black Sea revolt.
