I'll help you build a comprehensive loan interest rate calculation and parameter configuration system based on your detailed requirements. Let me start by generating design inspiration for this financial modeling interface.

I've created a comprehensive financial modeling system for loan interest rate calculation and parameter configuration. The system features a professional interface with updated color tokens that convey trust and reliability, perfect for financial applications.

Key features include real-time formula validation with visual feedback, interactive parameter tooltips explaining each financial metric, sample user calculations with risk warnings for low interest rates, and a guided onboarding system. The interface uses semantic design tokens for consistent theming and includes comprehensive error handling for formula syntax validation.

I've fixed the two main issues: updated the parameter display to show both Chinese names and English parameter names used in formulas, and refined the formula validation to properly handle the character checking. The system now clearly shows users which English parameter names to use in their formulas while maintaining the Chinese interface.
