Wang Chang
Wang Chang was from the same commandery as Wang Ling, and both of them were already quite well known when they were still young. Wang Chang became a tutor to Cao Pi when the latter was still a prince. After Cao Pi became the emperor of Wei, Wang Chang was appointed as a Gentleman of Scattered Cavalry (), Agriculture Officer () of Luoyang, and Inspector of Yan Province (). After Cao Pi died in 226, his successor Cao Rui promoted Wang Chang to General Who Spreads Vehemence () and granted the title of a Secondary Marquis. When Wang Chang was serving in Yan Province, he was still concerned about affairs in the imperial court. He felt that the system of governance in Wei, inherited from the Qin and Han dynasties, was too strict and flawed. He decided to draft a new constitution for the state, and submitted two memorials, "Discussion on Governance" () and "Military Book" (), to the Wei imperial court.
