Hi,

Thank you for your submission. I noticed a few points that need improvement:

1. Ensure there are spaces between Chinese and English text.
2. Please follow the formatting style of other model integration chapters. Additionally, your submission does not currently describe how to integrate with the Dify platform—this should be included.
3. The content should primarily focus on integrating with the Dify platform. If you need to reference your platform’s deployment program, you can provide a hyperlink to the relevant documentation.

If you have any questions, feel free to let me know.

Best,
Allen
