It is said that in the old society, rickshaws wore yellow vests and generally traveled in this car. Because of its low price, people call it a "scalper" car. Later, traffic developed, but train and bus tickets were hard to buy. Because rickshaw drivers often run in railway stations and bus stations, they are familiar with selling tickets at stations, and some people ask them for help to buy tickets. rickshaw drivers also get a certain tip, but not much. In fact, there were "scalpers" in the old society, but unlike now, they have developed into an industry, colluding with each other inside and outside, collecting money crazily and harming the interests of ordinary people. Supposedly, with the development of society, it should be convenient to travel. The reason why the "yellow cattle" can't fight is because of the interests.
