Having seen high-rise buildings, the director used extraordinary shooting skills to lead us into the world of insects. Unexpectedly, here, the normally "scary" bug gate shows a different kind of beauty. When you take a closer look at the world, you will find that the hair of the caterpillar is so smooth; the snails that snuggle up to each other are warm enough to make people cry; the diligent dung beetles deal with their dung balls every day; spiders use a small bubble as their restaurant underwater; longicorn beetles compete with each other like bulls. Every bug has never been idle to waste its time. The microcosmic bug world brings not only the visual shock to the audience, but also the truth that nature cannot tell to human beings.
