Dear Principal,
My name is Johnny.I have some complaints about the school.The first one is about the library.The wifi in the library often becomes inaccessible,especially when there are many users try to connect it.The second issue is some rooms of the dormitory don't have balconies.Finally,school's basketball courts,in my opinion,are not enough.Thank you for your time.I am looking forward to your reply.
King Regards,
xx
