He is nicknamed "Nine Fingered Divine Beggar" after he severs one of his fingers to remind himself to be more time conscious as he has once failed a mission after overindulgence in fine cuisine.  He plays a supporting role in the first novel by imparting his skills to Guo Jing and Huang Rong.  Huang Rong succeeds him as the Beggars' Sect's chief.
