Helan Chushi, the son-in-law of Minister of Personnel Hou Junji, was a Palace Guard; the Crown Prince knew that Hou Junji had always been bitter and vengeful, and he summoned Helan Chushi several times to escort Hou Junji to the East Palace, and sought his advice on staying safe; Hou Junji believed that the Crown Prince was foolish and incompetent, so he wanted to take the opportunity to use him; he therefore incited the Crown Prince to rebel, and raised his hands in front of the Crown Prince, saying, "These are a good pair of hands, and should be put to use for Your Highness."
