In order to crack down on drug trafficking syndicates that sell new drugs, the General Bureau of Criminal Investigation and the General Administration of Narcotics jointly launched a joint operation and dispatched agents such as Du Dayong, Shen Rui, and Chang Min to infiltrate the drug traffickers. Du Dayong, with the cooperation of Tang Shuaishuai and others, gradually approached and disrupted the drug transportation lines. As the investigation deepened, a drug production base spanning two places and five provinces was revealed.
