did not dare to ask Xun You again about state and military affairs after that. Cao Cao often praised Xun You and once said, "Gongda is intelligent but appears foolish; he is courageous but appears cowardly; he is resilient but appears weak. He neither flaunts his talents nor brags about his achievements. You may be as intelligent as him, but you can't pretend to be foolish as well as he does. Even Master Yan and Ning Wu cannot be compared to him." When Cao Pi was still Cao Cao's heir apparent, his father told him, "Xun Gongda is a role model for people. You should treat him courteously and respectfully." When Xun You was ill, Cao Pi visited him and knelt down beside his bed; such was Cao Pi's level of respect for Xun You. Zhong Yao also once said, "Every time I plan something, I'll carefully think through it again and again until I'm certain that I can't make any more changes. However, after consulting Gongda, he always has new insights to offer." Xun You created 12 strategies for Zhong Yao. Zhong Yao died before he managed to finish writing a book about the 12 strategies, hence some of them were lost. The historian Pei Songzhi thought it was a huge pity that Xun You's strategies were lost because Zhong Yao died at the age of 79 – some 16 years after Xun You's death – so he probably should have had ample time to finish writing the book. The Wei Shu recorded that Cao Cao once said, "I have travelled with Xun Gongda for over 20 years. I can't find any fault with him." He also said, "Xun Gongda is truly a virtuous man; he fits the saying '(he is) benign, upright, courteous, temperate, and complaisant and thus he gets what he desires.' He is exactly the man described in this quote by Confucius: 'Yan Ping Zhong knew well how to maintain friendly intercourse. The acquaintance might be long, but he showed the same respect as at first.'" The Xun Yu Biezhuan (荀彧別傳; Unofficial Biography of Xun Yu) recorded that Cao Cao once commended Xun Yu and Xun You for their excellent judgments about people's talents and said he would never forget them for their contributions. The Fu Zi mentioned that someone, who lived around the same time as Xun You, once asked if there were any virtuous
