By constructing the perspective of the fetus in the mother's womb, the film expresses the harmonious symbiosis between man and water, life and nature in an ideal state, and the eternal cycle of the reproduction and rebirth of life under the influence of water and nature. This is an experimental short film without dialogue. The audience will follow the perspective of the fetus in the mother's womb, that is, the perspective of the girl in the short film. Following the image and sound of the water flow in the dream, the audience will meet her mother, that is, the pregnant woman in the short film, in a surreal consciousness space to find the source of life. I hope to use pure film methods, relying on the image itself and sound design to show the harmonious symbiotic relationship and state between man and water, life and nature that is close to eternity, so that the audience can rethink the position of human beings and the natural environment and convey the wonderful emotions of life and its existence.
