Now I just adjust and put more information finish. I would like you check the paper. Should how I amend or adjust it. Then, I would like to know this text "if not see question 7, it should read staff and and staffs." You mean I should look question number 7 and I should check part staff section. Am I understand correct or not? Also, I just experiment questionnaire to check reliability. So can I start to explore the actual locations.
