What sensitive military information did the ex-soldier share with a foreign espionage agency?

According to China's Ministry of State Security, the ex-soldier transmitted photos and videos containing highly sensitive military intelligence to a foreign espionage agency through social media platforms. The shared information included details about troop deployment locations, weapon configurations, and specific information about military barracks positioned near border areas. This security breach represents a significant compromise of national defense information, particularly concerning military assets in strategically sensitive border regions. The disclosure was officially reported by China's Ministry of State Security in a statement released on Tuesday.
