Sima Yu
In 299, Empress Jia orchestrated the arrest of Sima Yu, heir to the throne, by convincing him while drunk to copy a text that said, amongst other things, that Emperor Hui should abdicate in favor of him. Empress Jia then presented the copied text to Emperor Hui, who then decided to execute his son. Empress Jia desired the punishment to be carried out immediately but Emperor Hui instead merely deposed Sima Yu and kept him under house arrest for the time being.
