Along with the ups and downs of the nation's history, the Vietnamese script has been born for more than 400 years. There have been many studies on the origin and process of the formation and development of the Vietnamese script, initially it was determined: The national language is a written language created by Western Catholic clergy, specifically the Jesuit missionaries, from the Latin alphabet to write the voice of the Vietnamese people at the beginning of the seventeenth century. At the beginning of the project, there was the collaboration of some Vietnamese people. After that, it was the Vietnamese people through the periods who contributed to perfecting this type of writing. However, the history of the birth of the Vietnamese script still has a number of issues that need to be further researched such as: the place of birth (embryo) of the Vietnamese script, the role of the missionaries in missions related to some figures such as Tran Duc Hoa, Alexandre de Rhodes...
