Jiu Mu, born in 1983, is a member of Fujian Province Writers Association. He had created a variety of types of fictions. However, most of them were written for practice and did not have a clear creative position. Jiu Mu began to show a strong interest in the creation of detective fictions after reading the series works "e;Kindaichi Holmes"e; written by the famous Japanese writer Yokomizo Masashi. Jiu Mu published "e;Seven Drop"e; and "e;Demons in Chat Room"e; in journals, both of which were highly praised. He also published detective novels such as "e;Heavy Case Tracking"e;, "e;Heavy Case Arresting"e; and so on.
