Dear Sir/Madam,
I'm Li Hua, currently participating in a short-term language training in Oxford and planning a tour of London this Sunday. Concerning the advertisement on your website, I'm writing to sincerely inquire some additional information about this trip.
Primarily, I'd like to know if there is a discount for students. Additionally, are entrance fees and lunch included in the package? Meanwhile, when is the shopping time? Lastly, it would be better if I could be notified the time to return since I've got assignments to finish.
Sir/Madam, your kindness to furnish me with this information is greatly appreciated. I look forward to your response at your earliest convenience.
