Chuangyu Wang enhanced localization quality for the sandboxie-plus/Sandboxie repository, focusing on Chinese translations for Sandboxie Plus and Sandman. Over two months, Wang standardized UI strings, improved error messages, and refined interface elements such as the 'Test Settings...' button, ensuring consistent terminology across components. Using TypeScript and leveraging internationalization and localization skills, Wang delivered three translation updates for zh_CN and zh_TW files, improving clarity and user experience.
