Reporter Chai Jing's documentary "Under the Dome" is of great significance and can arouse the public's attention to environmental protection. However, there are some places in the documentary that are not rigorous enough, and there are many unscientific or too one-sided and untrue pictures, so this documentary was finally banned.

Chai Jing was originally a CCTV reporter. One year after his resignation, he released a documentary about the in-depth investigation of air pollution, Above the Dome, which immediately attracted public attention. This documentary mainly tells what kind of harm air pollution will bring to human beings, what causes air pollution and so on. Soon after it caused a great response on the Internet, the documentary was banned, and many people were curious about the reasons.

In fact, the main reason why Under the Dome was banned is that there are many untrue and one-sided pictures in the film, which will mislead human beings, and this documentary is highly concerned. In order not to affect people's correct understanding, it was finally decided to ban the documentary.
