The true identity of the sparrow owner

The relationship between the characters in Sparrow is confusing. In the original updated story, it is not clear who is the real sparrow, and I don't know how many sparrows there are. The audience thinks that Chen Shen is a sparrow, yes, but in fact, Chen Shen is not the only sparrow.

After Shen Qiuxia's death, Chen Shen has been using the code names of "Prime Minister" and "Sparrow". In fact, Chen Shen developed into a "sparrow" and a "prime minister" in the later stage of the plot. From then on, Chen Shen fought for the liberation of China as a double undercover.

Li Xiaonan's real identity is a female agent, and naturally she lives in darkness. But the three provinces in Jiangsu are different. Su Sansheng's identity is aboveboard in dealing with the Chinese Communist Party. So later, after Li Xiaonan was betrayed, he was interrogated by Su Sansheng until he was finally killed by Su Sansheng.

Tang Shanhai and Xu are both undercover of the Chinese Communist Party. Tang Shanhai and Xu pretend to be husband and wife together. In fact, Tangshan Sea has long been full of enthusiasm for Xu, and Xu has gradually become dependent on Tangshan seafood. When Tang Shanhai was killed by Bi Zhongliang, Xu made up his mind to avenge Tang Shanhai one day. So Xu stayed in Shanghai and fought for the liberation of China.
