Dear Ms Smith,

I’m writing to ask whether you could do me favor. I’ve just finished an essay naming “Differences between traditional Chinese and Western festivals”, so I’m not sure whether it is well written. To be honestly, I’m not that familiar with some traditional Western festivals. That’s because I’m turning to you for help. I’d appreciate it if you could spare some time to look into my essay for possible mistakes and polish them. Also, I’m looking forward to your valuable advices. My essay has been sending to you along with this email. I hope it won’t cause you too much more trouble.

Thank you in advance.

Yours sincerely,

Li Hua
