The story about Marquis Bảo Nghĩa is taught in Vietnamese textbooks and many places in Vietnam are named in honour of this national hero.

He was asked about the prospect of being a Prince for the Yuan dynasty, he answered by a phrase which became famous in History of Vietnam:[2][6] 寧為南鬼，不為北王 Ninh vi Nam quỷ, bất vi Bắc vương.Ta thà làm ma nước Nam chứ không thèm làm Vương đất Bắc.I prefer to be a ghost in the South than a King in the North.

There was a difference between "Story of Annam" in History of Yuan and Đại Việt sử kí toàn thư about the date of the event at Đà Mạc, the Vietnamese work dated the battle in February while the exact day of the battle in the Chinese book was January 21 of Lunar calendar.

According to modern historian Lê Mạnh Thát, the Chinese book might be more accurate in this case because most of the original historical records of the Trần dynasty were destroyed by the Ming dynasty during the fourth Chinese domination over Vietnam so maybe Ngô Sĩ Liên committed an error in copying this event.

[1] Stories about his spirit and action are taught in schoolbooks of several grades while a main street in Hanoi and many other places in Vietnam are named in honour of this national hero.
