The open ending should be understood by the audience themselves. According to the TVapp of Korean drama, the ending of the Korean version of "Drug War" is open. At the end of the film, the ultimate boss, Mr. Li, and police officer Zhao confront each other in the wooden house. From the double guns on the table, we can see that they must die. With one shot, the fire in the house suddenly went out and the film ended. Whether officer Zhao is dead or Mr. Li is dead needs the audience to know for themselves. The Korean version of "War on Drugs" tells the story of Zhao Yuanhao, the leader of the anti-drug team, and Yongle, a member of the drug trafficking organization, jointly arresting Mr. Li, the leader of South Korea's largest drug trafficking organization.
