The delivery person intercepted 100 deceptive promotional flyers.

The State Security Department released a case: In February 2025, courier Li Yan was carrying out her collection and delivery work as usual when a middle-aged man with an anxious look entered the business hall, carrying a tightly sealed paper box. His fingers trembled slightly as he filled out the waybill, and he deliberately avoided eye contact with the staff. Li Yan immediately noticed something was amiss and proceeded to carefully inspect the items being sent. Upon conducting an inspection of the contents, it was discovered that the paper box contained paper materials with the name of a certain government agency, including sensitive and confidential information. In order to prevent any actions that may harm national security, Li Yan promptly reported the incident to the local national security agency. Upon investigation, it was found that the paper materials sent by the sender were fake government documents with fraudulent intent. Thanks to Li Yan's timely discovery, nearly 100 pieces of fraudulent propaganda flyers were prevented from entering society.
