What are the big loopholes in the TV series Kite?

The first loophole was that Zheng Yaoxian was informed by the Scout secretariat to go to Dai Mansion in Shenxian Cave to meet Dai Li. Zheng Yaoxian clearly knew that the underground party in Shancheng and the people in Central China hated him, but he was still alone. Is this to show heroism? Moreover, the people ambushed by the central government clearly wanted to kill people with knives, but everyone arrived at the scene, and no one really killed Zheng Yaoxian.

The second loophole is that the shadow in Yan 'an sent a message to Dai Li in the mountain city and a top secret message, but the underground radio station and Zhong Tong in the mountain city knew nothing about it, which is extremely puzzling. In addition, radio stations in other regions have not found it, which is amazing.

The third loophole is that Zheng Yaoxian clearly prepared to turn against Xu Baichuan and others, but gave Xu Baichuan a signal to wake him up. This situation is very inconsistent with Zheng Yaoxian's thinking. He should know that once Xu Baichuan is caught, it is also a great threat to himself. In the play, Zheng Yaoxian also revealed whether Xu Baichuan would betray him, and he didn't know the result until the moment he died. Obviously, it is unreasonable for Zheng Yaoxian to prepare the contact code with Xu Baichuan in advance.

The fourth loophole is Zheng Yaoxian's criticism of Han Bing. Before Chiang died, the secret service sent an extremely obvious little spy to see Chiang, and then transferred Gong Shu to Hong Kong, which was very coincidental. As a thoughtful agent, Zheng Yaoxian has no doubt about this situation. Even Ma Xiaowu has gone to Hong Kong to perform a task. Ma Xiaowu made it clear that as soon as he entered Hong Kong, he found himself being targeted. Ma Xiaowu suspected that someone tipped him off here in the mountain city, but Zheng Yaoxian paid attention to several people Ma Xiaowu saw, which was not in line with normal thinking. Ma Xiaowu had no contact with these people when he entered Hong Kong. How did these people know who he was or when he arrived in Hong Kong? Obviously, not these four people. Of course, some of them also sell information, but as a senior agent, Zheng Yaoxian got such a simple conclusion and was so arbitrary, which is obviously not normal. However, this is also the foreshadowing of great sadness when Zheng Yaoxian knew that Han Bing was a shadow in his later period.
