Documentary is a film and television art form that takes real life as the creative material, real people and real events as the performance objects, and artistically processes and displays them. Its essence is to show the truth and use it to arouse people's thinking. The core of documentary is truth.

2. A good movie brings a good story to the audience; And a good documentary opens a picture of history for us, which makes us understand the unique culture and reflect on ourselves.

In this case, we can draw some preliminary conclusions. Documentary can bring us some thoughts about national culture and human self-reflection.

4. Just like the documentary "China on the Tip of the Tongue", it tells the diversity of China's food culture and the origin of our food, so that we can know its root and explore its source.

5. There are also some reflections on our own human behavior, such as a documentary about the Northeast Leopard. After we and our children are caught by hunters, we would rather kill our children than let them live in chains. Is strict maternal love better able to show the filth of our human behavior?

6. Documentaries are facts. It is like a tiny embroidery needle, which stings our skin all the time, let us know the world and explore its truth.
