Dear Sir or Madam, I'm writing to enquire about the tour guide training courses at SGV Vocational School. I'm interested in becoming a tour guide and I'm excited about the opportunity to travel and explore different cultures. First, I would like to know more about the course curriculum and what topics are covered. In addition, I wonder if there are any specific requirements or materials I need to prepare before the course starts. I would appreciate it if you could tell me more about the apprenticeship program and how it works. It would be great if you could also provide information about the course schedule and duration. I look forward to hearing from you. Yours sincerely, Minh
