The article points out the mistakes in "Nam Ky phong tuc nhon vat dien ca" by Nguyen Lien Phong, reprinted in 2012 by the Literature Publishing House, with the introduction and annotation of Nguyen Q. Thang. That edition is very careless with many spelling errors, which makes readers confused. The introduction and annotation also contain many errors, from the perspective towards the author Nguyen Lien Phong to the interpretation of place-names, administrative borders, historical events and figures... Those errors seriously decrease the quality of a valuable work of geography, history and culture in Southern Vietnam in the early twentieth century.
