Dear Jack,

I hope this email finds you well. I am writing to discuss our upcoming survey on the protection of old houses in the ancient town. I propose that we start by identifying key areas with historical significance and then create a questionnaire to assess local residents' opinions on preservation efforts. We could also interview local authorities to gain insights into current policies. I would appreciate your thoughts on this plan and any other suggestions you might have. Please let me know your availability so we can schedule a meeting to finalize the details. Looking forward to your input.

Best regards, Li Ming
