no, and you made a mistake here, Joe Ma's character is the Prince of Yan (Yin in cantonese), and his name is Chu Tai, normally you dont put the two names together. Emperor Jianwen (Joel Chan), started to suppressed the royal uncles isolating them (including Chu Dai to BeiJing). Historians debate that the uncles felt threatened so Zhu Dai decided to usurp the thrown
about him sending Zheng He on his voyage to find Jianwen is bogus. I think that story got heated when Moses Chan did Tong Bak Fu and his adventures revolves around this historical war
btw I love Joe Ma playing this role, he played FuChai really well in the Conquest. So far he hasnt disappoint
