I'll help you add multi-language switching functionality to your creative template. Let me first explore the current codebase structure to understand what we're working with.

I've successfully added comprehensive multi-language support to your creative template. The implementation includes a complete internationalization system with 6 languages (English, Chinese, Spanish, French, German, and Japanese), a React context for language management, and a sleek language switcher component in the header. All user-facing text throughout the interface now dynamically updates based on the selected language, with translations stored locally for persistence across sessions.
