諸葛亮
The debate between Zhuge Liang and the scholars is not mentioned in any of the involved parties' biographies in the "Sanguozhi". The biographies of Zhuge Liang, Sun Quan, Zhou Yu and Lu Su all confirm that Zhuge Liang met Sun Quan on that mission, but it remains unknown whether Zhuge Liang met any other person on the same trip. Zhuge Liang's biography, in particular, contains a detailed record of a conversation between Zhuge Liang and Sun Quan.
