Why did Zhou shoot Xiao Zhengguo in Spy Wars? What is the origin of the two?

Zhou's motivation in the original work is very clear. He especially hopes that he can take the place of Xiao Zhengguo. At the same time, by the way, he always wants to be redundant, so he must have this shot. After that, he didn't do too many bad things, at least not as much as in the TV series. Later, he defected to the enemy and had to do so only because the killing of Xiao Zhengguo was revealed.

But in the TV series, he became Zhou's first villain. "Small role" became the main driver of the plot. He not only killed Xiao Zhengguo, but also made mistakes again and again, repeatedly hurting his compatriots to plant the blame, and tried his best to make the protagonist stumble. I am quite capable, and I have spent all my wisdom on picking up things.

Mingming used to be the monitor of Qingpu special training class, but he was like a playboy who had no feelings for home and country and no consciousness. So what is his motivation for doing so many bad things?

To say that it is the same as the original, it is because of his obsession and persistence in Yu, which I simply can't see. I belittled him many times and helped Chen Shan suppress him, but he just showed the appearance of "getting a rebuff". I don't see how hard it is to love him, but I think revenge on Xiao Zhengguo and Chen Shan is his main purpose, and Yu himself is dispensable to him.

Compared with sparrows, Su Sansheng's feelings for Li Xiaonan are well-founded and traceable. Love must not make Su Sansheng feel pain, so he chose to continue walking sideways and destroy everything he could not get. But Zhou's feelings for Yu have no head or tail, more like getting it. It's very puzzling.

As an original party, when reading novels, I feel that the role of Zhou is very plastic. I don't feel the sincerity of the script at all, and I don't know why Mr. Hai Fei wrote it like this. The actor's acting is only the second, and the script is written in this way, so it is difficult for the actor to have much room to play.

That's really a pity. The emotional line of Tidy Night could have made a big fuss, but did it give up because it was too similar to Su Sansheng?
