Why did Qiudong Zheng pretend to be Qin Fei in Hunting Field? How did he get caught?

It is reported that in the TV series "Hunting Field", because Qiudong Zheng was in prison, he ran into a wall everywhere after he got out of prison, and he was not trusted to find a job. In order to integrate into the society and make progress in her career, Qiudong Zheng pretended to be Qin Fei, who had passed away, and used Qin Fei's identity to find a job. After visiting Qin Fei's home and classmates' home, I learned all the basic information about Qin Fei and interviewed for a job as Qin Fei.

From here, we can boldly assume that when will Qin Fei's identity in Hunting Field be seen through? First of all, even if Qin Fei's family is a mountain village in Guangxi, his parents don't often go out, but that doesn't mean that students who know Qin Fei don't go out. It is quite common to meet alumni and classmates in the workplace, and Hugh's career behind the hunting ground is getting smoother and smoother, so he is more likely to be caught in public. Secondly, in the publicity before the hit of Hunting Field, Hugh kept talking about how Qiudong Zheng was on the show, and never mentioned how Qin Fei was, which proved that he was still alive as Qiudong Zheng.

Besides, it is illegal to borrow someone else's identity. If everyone who is released from prison is such an impostor, wouldn't this society be in chaos, then the whole road would definitely be impassable. Finally, viewers who have seen Hunting Ground should know that Hugh applied for this position as Qin Fei! But it was finally revealed by people who had seen Qin Fei himself.
