He says that he admires his father's valor and that he wishes he could meet him in person. He also says that his father has always treated him in high regard. Xuan zhou tells his father that he cannot believe that the prince will acknowledge him. The prince is like a "super war god" in the military, he is the "national idol" of the imperial court.
