Make Chinese emails clearer and more respectful without adding fake details or over-formal language.
Polite Chinese emails are not just softer versions of direct messages. They usually clarify who you are, what you need, and what action you hope the reader will take.
Keep the request clear
A useful structure is: greeting, short context, request, deadline if needed, and a respectful closing.

Do not invent formality
Overly formal words can make a message feel unnatural if the relationship is ordinary. The right tone depends on whether you are writing to a teacher, manager, customer support team, or business contact.
Good rewriting should preserve names, dates, numbers, products, prices, contracts, and commitments. Tone can change, but facts should not.
Check before sending
After rewriting, review the names, dates, numbers, and promises. AI can make language smoother, but the sender is still responsible for the final content.
If the message is important, compare the rewritten version with your original draft line by line before sending.
