From June 20 to 22, 2025, the Huawei Developer Conference (HDC 2025) was held in Songshan Lake, Dongguan. Technology upgrades such as HarmonyOS6.0 and Pangu Big Model attracted industry attention. Against the backdrop of the country's accelerated promotion of the information technology application innovation strategy, the localization migration of government systems has become a core issue in the modernization of digital governance. Huixin Technology's smart law enforcement solution based on HarmonyOS made its debut at the "Hongmeng Ecosystem Industry Solution Forum (Northbound)", publicly sharing for the first time the full-stack localization practice path of "operating system capabilities + government scenarios", providing another feasible answer for building a secure, controllable and flexible digital base for local governance.
