Is Tang Xiao undercover?

In the plot of Punishment, it was found that Tao Qiu was undercover. Before that, he always thought that Tang Xiao was. On several occasions, he secretly sent messages to others. Every time I send a message, it's such a coincidence. He didn't expect it to be undercover, and the political commissar Yan actually started to lay out from Australia.

In fact, in retrospect, the director hinted many times, but the audience set the target of doubt on Tang Shaowen.

This is Zhao's first hospitalization. At the gate of the intensive care unit, Zhao Laosan sent someone to the airport to block Chang Zheng. At that time, both Tang Shaowen and Tao Qiu heard it. But the director gave Tang Shaowen a picture of secretly texting.

The second time, there were three people on the bus, Zhao Laosi, Tao Qiu and Tang Shaowen. Zhao Laosi told Tao Qiu that Zhao Laosi's waking up must be kept secret. At that time, the director gave another shot to whom Tang Shaowen immediately sent a text message.

The third time was also Zhao Laosi, Tao Qiu and Tang Shaowen. Zhao Laosi told them that under the guise of celebrating the 60 th birthday of the old man, he would ask the commemorative father to say something and prepare the Zhao family's plan to transfer their property to Australia. Just say that finish, Tao Qiu left normally, but Tang Shaowen said to Tao Qiu, there are things, I won't take his car today.

Obviously, every important clue depicts Tang Shaowen's abnormal expression and movements, which makes people suspect that the director is intentional and makes the audience mistakenly think that undercover is Tang Shaowen. According to the reverse thinking, since it is so obvious, it means that undercover may not be Tang Shaowen, so only Tao Qiu is present every time.
