Dear Paul,

Thank you for your email regarding your assignment on an ancient Chinese scientist. I am writing to provide you with some practical advice.

It is advisable to focus your research on a specific scientist, such as Song Yingxing. This approach is designed to narrow the research scope and establish a solid foundation for your speech. Regarding your request for assistance, we would appreciate it if you could prepare a preliminary outline based on this recommendation.

Please let me know if you need any further information.

Yours sincerely,
Li Ming
