假如你是李华,最近收到一封英国笔友Tom的来信.他希望了解你校如何维护学生在校期间的安全.请你写一封英语回信,介绍你校的做法,如重视安全问题、加强安全教育、增加保安人员、来访示证登记等!

Hi, Tom,
How are you doing? I received your last letter concerning our school's public safety. I have to say that though we are located in a comparatively unsafe neighborhood, our school does make a lot of effort on public safety. In the past few years, our school has doubled the number of security guards. The school also offers escort service with the safety patrol. Sign-in is required for every visitor. Our teachers also give security lessons which teach us how to deal with emergency.
Thank you for your concern, but I really feel safe in my campus. Please rest assured. Looking forward to hearing from you again.
Yours
Hua Li
