Emperor Shao soon became known for spending much time on frivolous matters with impertinent attendants, even during the three-year mourning period, and not on studies or important matters of state. Xu, Fu, and Xie became convinced that he was not a fit emperor, and considered deposing him. However, they had even lower opinions of his oldest younger brother, Liu Yizhen (劉義真) the Prince of Luling, so they first stoke the rivalry that Emperor Shao already had with Liu Yizhen and then accused Liu Yizhen of crimes. In 424, Emperor Shao reduced Liu Yizhen to commoner rank and exiled him.
