Why did Wang Can Bao Qiang buy a real train ticket and Xu Zheming bought a fake one?

The part where people get on the train at the end of the road is not the most classic in the whole play, but it is wonderful. As a rich boss with social status, Xu zhēng made a hard-seat car because his subordinates were incompetent. Most people think that he has had enough grievances. However, his ticket was taken by his client. Although there is no specific place to get it, it is certain that it was bought at a regular ticket office. Most people think that Xu zhēng's tickets are fake, but not all scalper tickets are fake, and most scalper tickets are real. Very few scalper tickets are fake. In the case that the conductor is confused at the scene, both Xu zhēng and Wang are actually grabbing Xu zhēng's ticket. This shows that Wang also thinks that Xu zhēng's ticket is real, and his ticket may be fake, so Wang's ticket is also bought by scalpers. So they are all scalper tickets. In a word, it was arranged by the director.
