Changes Made:
1. Consolidated Language-Specific Configurations:
   - Moved all `if lang == 'cn'` assignments into a single conditional block.
   - Reduced redundancy and improved readability.

2. Simplified Protocol Initialization:
   - Created `MindSearchProtocol` objects directly without extra steps.
   - Streamlined configuration to make the code more concise.

3. Optimized Dictionary Creation:
   - Used a dictionary literal for `searcher_cfg` to avoid repeated `dict()` calls.
   - Improved efficiency and readability.

 Why These Changes Were Needed:
- Readability: Grouping related configurations together makes the code easier to follow and maintain.
- Efficiency: Reducing redundant code and simplifying structure helps in better performance and less error-prone code.
- Maintainability: A cleaner, more concise codebase is easier to debug and extend in the future.
