What are the big loopholes in the TV series Kite?

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

The second loophole is that the shadow as far away as Yan 'an sends messages to Dai Li in the mountain city, sending top secret messages, but the underground radio station and Zhong Tong in the mountain city know 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 wake-up signal. 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 until his death. 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 he found himself being targeted as soon as he entered Hong Kong. Ma Xiaowu suspected that someone tipped off 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 not come into contact with these people when he entered Hong Kong. How do these people know who he is or when he arrived in Hong Kong? Obviously, not these four people. Of course, some of these people sell information, but it is obviously not normal for an old agent like Zheng Yaoxian to reach such a simple conclusion and be so arbitrary. However, this is also the foreshadowing of great sorrow when Zheng Yaoxian later knew that Han Bing was a shadow.
