왕망
In 3 AD, Wang Yu formed a conspiracy with his teacher, Wu Zhang (吳章), his brother-in-law, Lü Kuan (呂寬), and the Weis, to try to break Wang Mang's dictatorial hold. They decided that they would create what appeared to be supernatural incidents to make Wang Mang concerned, and then have Wu Zhang try to persuade Wang Mang to transfer power to the Weis. Wang Yu instructed Lü Kuan to toss a bottle of blood onto Wang Mang's mansion door, but Lü was discovered by Wang Mang's guards. Wang Mang then arrested Wang Yu, who committed suicide, and his wife (Lü Kuan's sister) Lü Yan (呂焉) who was then executed. Wang Mang subsequently executed Wu Zhang and the entire Wei clan, except for Consort Wei. It is not known what happened to Lü Kuan, but it is unlikely he could have escaped death.
