TOXICMAN: Ale zaslouží si taky doplnit, proč:
In 1232, after usurping the Lý dynasty, Trần Thủ Độ forced the descendants of the Lý to change their surname to Nguyễn. When Hồ Quý Ly overturned the Trần dynasty, he killed many of their descendants so when the Hồ dynasty collapsed in 1407, many of his descendants changed their surname to Nguyễn in fear of retribution.In 1592, on the collapse of the Mạc dynasty, their descendants changed their surname to Nguyễn. In late 16th century, the Tư Mã clan from Thanh Hóa changed to Nguyễn and settled in Cochinchina. When the Nguyễn dynasty (the descendants of the Nguyễn Lords) took power in 1802, some of the descendants of the Trịnh Lords fearing retribution changed their surname to Nguyễn, while others fled north into China. The Nguyễn dynasty awarded many people the surname Nguyễn during their rule, and many criminals also changed their surname to Nguyễn to avoid prosecution.
