Also known as Xie Lou, formerly the Second Prince and a strong contender for the throne. After the Late Emperor's succession edict, his name was changed from a noble name to the ordinary name Lou. He now presents himself as indifferent and detached from court affairs, slacking off and avoiding responsibility. During a court discussion about Yellow River flood repairs, he deliberately asked where the Yellow River is to shirk the task. The Emperor privately hopes he will pull himself together.
