What is the identity of Suo Dong in the black storm?

During the black-sweeping storm, Suo Dong and Luo, the leader of the Central Supervision Team, came down from the Central Committee to investigate the problem of black-sweeping and evil-eliminating in Lvteng City. During the supervision, he was mainly responsible for the safety logistics of the whole supervision team.

After Luo and his party came to Luteng City, Suodong's first task was to stay in a hotel in Luteng City. In order to prevent eavesdropping, Luo arranged for Suodong to check whether there were cameras or eavesdropping devices inside and outside the hotel. After the inspection, Suodong reported that Luo He Shan did not find any suspicious devices.

In addition, his scene is generally Luoshanhe, where Zhao and He Yong talk about the progress of the case in a pavilion by the river, and stand alone beside the pavilion to observe the situation around the pavilion. SuoDong at this time is more like a bodyguard around Luo Shanhe. The alert eyes especially have the professional quality that a bodyguard should have.

Is Suodong's identity just the head of logistics support in the supervision team, as he seems? Or is there something else, a mole in the supervision team? Many voices on the Internet say that Suo Dong is a spy in the supervision team. Until the final finale, it was not directly explained whether Suodong had a second identity, which left more room for thinking and guessing for everyone outside the play. In fact, I personally prefer to think that Suodong is simply the person in charge of security work.

Because Suo Dong himself has no motive and opportunity to provide an umbrella for evil forces. First, Suo Dong Gengben and Gao Mingyuan have no chance to meet. He doesn't work in Zhongjiang province, nor is he from Zhongjiang province. He left the central government directly with Luo. Such a person who has nothing to do with Gao Mingyuan doesn't need to act as an umbrella for Gao Mingyuan. Second, although Luo's conversation was eavesdropped in the early stage, and Suodong said that no eavesdropping equipment was found in the early stage of inspection, it was suspected to be a mole. However, after the whole story, there is no directional scene to prove that Suo Dong is cooperating with the evil forces in Lutengcheng to avoid investigation or provide help, so from this perspective, Suo Dong's identity cannot be reflected as a spy under surveillance.

In fact, the plot setting of the character Suodong is to make the plot more tortuous and suspenseful, which proves that the evil forces in Lvteng City are very huge. Even the well-trained personnel of the Central Inspection Team in charge of security logistics dare to install eavesdropping equipment in the hotel and kill people under the eyes of the monitoring team.
