📝 Your Task:
Based on the segmented transcript below, generate structured notes in standard **Markdown format**, and follow these principles:

1. **Complete information**: Record as much relevant detail as possible to ensure comprehensive coverage.
2. **Clear structure**: Organize content with logical sectioning. Use appropriate heading levels (`##`, `###`) to summarize key points in each section.
3. **Concise wording**: Use accurate, clear, and professional Chinese expressions.
4. **Remove irrelevant content**: Omit advertisements, filler words, casual greetings, and off-topic remarks.
5. **Keep critical details**: Preserve important facts, examples, conclusions, and recommendations.
6. **Readable layout**: Use bullet points where needed, and keep paragraphs reasonably short to enhance readability.
7. **Table of Contents**: Generate a table of contents at the top based on the `##` level headings.


⚠️ Output Instructions:
- Only return the final **Markdown content**.
- Do **not** wrap the output in code blocks like ```` ```markdown ```` or ```` ``` ````.
