When Pei Ruhai was found to be a traitor, party member in the underground of Shanghai Railway Station was forced to evacuate to prevent Pei Ruhai from being dismembered after leaking secrets. As the plot progresses, you will find that Pei Ruhai is not the only traitor, and the following three people are all suspected:

A, underground party member Chen Lie Pan Yueming handed Chen Lie a secret document, let him leave the apartment with the file. Chen Lie did not leave after escaping from the apartment, but returned to the apartment dressed as a driver of the Secret Service. He knocked out Tang Xianping, but didn't kill him. Usually, Chen Lie pretended to be a driver to avenge Pan, but at this time he left. It was Chen Lie's actions that exposed the secret documents and made Tang Xianping suspect that the documents were not burned.

Second, the innkeeper's minions, proprietress and minions are all underground party member in Shanghai Station, in order to protect secret documents. When the proprietress wants to hold a group meeting, she implicitly asks who it is. When he learned that it was Wu Chongxin, his expression changed slightly. Moreover, his reaction after seeing Wu Chongxin was unnatural and suspicious.

3. Qiu Shaolin, owner of antique shop? Qiu Shaolin is Wu Chongxin's aide. When Ma Tianmu and Chen Lie asked to see Wu Chongxin to explain the emergency, Qiu Shaolin refused to let them meet, saying only that Wu Chongxin was absent. Qiu Shaolin's attitude is also very doubtful. When Ma Tianmu found out that Tang Xianping wanted to catch the leader of the underground party, Qiu Shaolin looked indifferent, like staying out of it, and didn't worry about party member at all.

From the above, it can be seen that Pei Ruhai is not the only traitor in the play Passer-by. The story clues and characters of this drama are very rich, and the plot is compact, and every detail is laying the groundwork. As a spy war film, it has a visual style difference from the plays such as Pretender and Latent, and has achieved a breakthrough. Finally, I hope that domestic dramas will get better and better.
