Zhao Degang is the Director of the Committee Office. He is stern, decisive, and authoritative. He initially questions Zhang Zhaodi's accusations but becomes convinced after examining the bloodstained ledger. He orders the immediate arrest of Lin Jinguo and oversees the public confrontation at the machinery factory auditorium. He confronts Director Zhou Changzhou about factory interference and presents the ledger as evidence to the workers. His voice is low and hoarse, and he carries an unquestionable sternness. He is a key authority figure driving the investigation.
