Beijing Vocational Examination Network Deception Company. I signed up for the 4,600-yuan fire-fighting vocational examination clearance class and listened to it for a year. I signed up in July last year. I heard that there were two live classes every week for three months. 1 1 There was no live class in June, and the replay class of Beijing Vocational Examination Network in July this year could not stand it. I contacted the registration teacher and said that I resigned and the class teacher left me alone. I reported to the class teacher, and the assembled highway engineer charged 6900, saying it was an open-book exam at home. All this is a lie.
