Driver's license: Recently, the driving school informed Mr. Bi to have a physical examination before the theory test of subject one. After physical examination, Mr. Bi was found to have amblyopia in one eye. The driving school coach told him that he didn't meet the requirements, so Mr. Bi had to ask for a refund, and the coach asked him to deduct the 200 yuan fee. Mr. Bi asked whether it was reasonable to detain 200 yuan. Mr. Bi told reporters that after paying the registration fee, he didn't take any exams, didn't receive any information, and the driving school didn't invoice him. The reporter came to Chang 'an Driving School in changji city, Xinjiang. President Zhao told the reporter that if a student asks for a refund after registering at a driving training institution or a registration point set up by a driving training institution, the refund will be made in accordance with the Regulations on the Management of Refund of Students in Motor Vehicle Driver Training Institutions in changji city, which has been strictly enforced by Chang 'an Driving School. Zhao said: "According to Mr. Bi's situation, the Regulations on the Management of Student Refund of Motor Vehicle Driver Training Institutions in changji city stipulates that driving training institutions should refund their fees, and driving training institutions will not deduct any fees except the 100-200 yuan fees generated by registration fees, taxes and information fees.
