First, according to the requirements of the state, train tickets can only be purchased in two places. The first is the ticket window at the train station, and the second is a legitimate agency with qualifications for selling train tickets on behalf of others. The ticket windows at train stations are not allowed to charge extra fees, they can only collect according to the face value of the ticket. Agency points can only charge 5 yuan per ticket as a handling fee, overcharging is illegal, minor cases will result in the cancellation of agency qualifications, serious cases will face administrative penalties. Now let's talk about the operation of the agency points. In fact, the cost of agency points is not high. If you apply through normal channels, it only costs 20,000 yuan to obtain the qualification, and the monthly cost is less than 2,000 yuan. Therefore, the 5-yuan agency fee is completely able to ensure its operation. However, since the railway industry is monopolistic, applying for an agency point is a very complicated process, with astonishing black-market practices involved. To put it our way, if you manage to obtain the qualification with 500,000 yuan, it means you have found the right channel. Often times, even if you have the money, you still can't get the qualification.
