顧雍
Sun Quan often sent his palace secretaries to consult Gu Yong on policy matters. If Gu Yong approved, he had food and drinks prepared for the secretaries while they discussed and refined their ideas with him. If he disapproved, he appeared solemn and remained silent, and had no food and drinks prepared for them. The secretaries then scrapped their ideas and went back. Sun Quan once said: "If Lord Gu is happy, that means he approves your idea. If he doesn't say anything, that means he thinks your idea can be improved. When that happens, I will think through again carefully." This quote showed that Sun Quan had much faith and respect for Gu Yong.
