Is there any auxiliary police officer who becomes a director after becoming a full member?

Yang Kun grew from an auxiliary police officer to the youngest Hall. Black Tiger Temple Police Station of Liangshan County Public Security Bureau, Jining City, Shandong Province is located in the northwest of Liangshan County, where the Yellow River crosses the border. The terrain is complex and the public security situation is grim. In the past nine years, from the auxiliary police, the police to the director, Yang Kun has successfully completed the role transformation step by step.
