How did spy Cheng Lei find out?

After investigation, it was found that.

To say how her identity was detected, we have to start with a program. In this program, Cheng Lei talked and laughed with various economic experts, and his professionalism was really admirable. However, when talking about the current situation of China's economic development, her words gave her a clue, and the relevant departments took note of her, that is, "foreign countries know the current situation of China like the back of their hands".

Most people don't care too much about this sentence, but the national security personnel in our country noticed her behavior of changing the topic of the program immediately and diverting everyone's attention. I really doubt why a foreign journalist knows so much about China's economic development and the pride on her face when she said this.

After discovering her undercover identity, the relevant departments quickly arrested her and launched relevant investigations. It turns out that during his 20 years as the host of CCTV, Cheng Lei has been sending China secrets to Australia. The leaked information has caused hundreds of billions of losses to China's economy, and Cheng Lei will also pay for her actions.
