《史记·七十列传·袁盎晁错列传》
梁王想成为汉景帝的继承人，袁盎进言劝说，之后这种议论就中止了，梁王因此怨恨袁盎，曾经派人刺杀袁盎。
梁王欲求为嗣，袁盎进说，其後语塞。梁王以此怨盎，曾使人刺盎。
King Liang wanted to become Emperor Jing of Han’s heir, Yuan Ang advised against it, and afterwards this discussion ceased, and thus King Liang harbored a grudge against Yuan Ang, and once sent someone to assassinate Yuan Ang.
