The son of the Chief Historian, serving as an attendant to the Prince of the Commandery. He was tasked with escorting the Prince to Ling Mountain Temple after the Prince fell ill with a cold. He is observant and knows when to keep his mouth shut, as shown when he stays silent during the Prince's angry moment with Xu Nian. He pulled the still-bewildered Mo Yu with him and headed up the mountain when the Prince demanded everyone step away.
