張昭
Although Gu Yong always maintained a polite and respectful tone when he spoke up on issues in the imperial court, he was also known for standing by his principles and holding his ground when he had to. On one occasion, when Sun Quan sought feedback from his subjects on policy matters, Zhang Zhao used the opportunity to ask for a review of the laws. He presented the findings he collected over a period of time, and pointed out that the laws were too strict and the penalties for crimes were too harsh. Sun Quan did not respond to Zhang Zhao and instead turned to Gu Yong and asked him: "Sir, what do you think?" Gu Yong replied: "My observations coincide with what Zhang Zhao just described." Sun Quan thus approved Zhang Zhao's request for a review of the laws.
