Explanation:

1. **Iterate through the 'profit_list' array.**2. For each element in the 'profit_list' array: - Identify 'cn_' prefixed keys. - Create corresponding 'en_' prefixed keys. - Copy the values of 'cn_' keys to their respective 'en_' counterparts.

This process ensures that the data is accessible to a broader audience, making the information more comprehensive and user-friendly.
