In China, the mobile phone has replaced the traditional wallet, with platforms like 'Alipay' and 'WeChat Pay' enabling citizens to conduct daily transactions simply by scanning QR codes.

Beyond payments, China utilizes technology for smart traffic management and facial recognition, emphasizing the balance between efficient services and individual privacy. The core lesson for administrative reform is that true success in tackling bureaucracy lies not just in launching apps, but in creating effective channels for tracking citizen complaints and ensuring accountability and tangible responses.
