The Ministry of National Security announced the case: In February 2025, courier Li Yan carried out the delivery operation as usual. A flustered middle-aged man entered the business hall holding a tightly sealed carton. His fingers trembled slightly while filling out the face form, and his eyes deliberately avoided the staff. Li Yan immediately detected the abnormalities and immediately carefully examined the items she had sent. During the unpacking inspection, it was discovered that the carton contained paper materials marked with the name of an authority or unit, including confidential and sensitive content. In order to prevent acts endangering national security from occurring, Li Yan immediately reported it to the local national security authorities. After investigation, the paper materials sent by the sender were actually forged official documents of a state agency and were fraudulent. Due to Li Yan's timely discovery, nearly 100 fraudulent leaflets were prevented from entering society.
