陳興道
After being the commander in chief of Đại Việt's army with a supreme power in royal court, Trần Quốc Tuấn began to reflect on his father's last will and thus seek advice from his servants and surbodinates. The idea of taking over the throne was immediately opposed by Trần Quốc Tuấn's two most-trusted servants, Yết Kiêu and Dã Tượng, so did his eldest son Trần Hưng Vũ. While their opinions made Trần Hưng Đạo satisfied, his third son Trần Quốc Tảng, on the contrary, proved to support the plot in suggesting his father the story of Emperor Taizu of Song who founded the Song Dynasty by taking over the throne from Later Zhou. Trần Quốc Tuấn was so angry after hearing his son's response that he even wanted to kill Trần Quốc Tảng but was stopped by Trần Hưng Vũ. Afterwards, Trần Hưng Đạo Trần Quốc Tuấn decided to break off the paternal relation with his son.
