What are the details of the fifth episode of the white night chase?

The details of "White Night Chasing Murder" are:

1, the scars of two brothers

At the beginning of the plot, my brother chose to draw a scar on his face like his brother, but Guan Hongfeng just bowed his head, which was unreasonable, because he was an old criminal policeman, so he couldn't bear it. So the biggest possibility is that he knows the truth, but he can't let his brother take the blame. He feels a little guilty.

2. About the death of the delivery man.

Also, in the first case, the takeaway brother mistakenly entered Guan Hongfeng's home. Guan Hongfeng asked why he was let in, and Guan Hongyu said that he was afraid that two people would scream and attract attention. However, one question is whether Guan Hongyu didn't intend to let the takeaway brother go out alive, because when the two brothers confronted the takeaway brother, Guan Hongyu could easily defeat the courier, but he deliberately let his guard down and let Guan Hongfeng and the takeaway brother get entangled. Later, because the takeaway brother fell out of the window, he was hit by a car that was patrolled by Zhou, causing an accidental death.

3. Wang Zhige case

In Wang Zhige's case, his diamond ring has never been taken off, but the watch of a university professor who was blackmailed by Lu Siping many years ago has long been taken away, which shows that Wang Zhige should not be the first university professor to be arrested. Judging from the plot analysis, it should be Tang Ying, because later Tang Ying mentioned something that was blackmailed by Lu Siping, and later Wang Zhige forgave it and murdered Lu Siping together.

There are some other small details, such as Guan Hongyu ran away on February.13, and the pregnancy result of his girlfriend Yan' an was 1 1.4, so whose child is Yan' an? And when the last two brothers decided to turn themselves in, who ate the fish raised by Guan Hongfeng? In fact, there are still many details worth considering when watching the play carefully. Sometimes you may not find it once you look at it. It takes two or three brushes to find it.
