A clear stream referred to the fresh breath and refreshing feeling brought by the breeze. In literature, describing a person or thing as a clear stream usually means that they have fresh, concise, and pure characteristics that can make readers feel happy and comfortable. In a novel, if a person or thing is regarded as a clear stream, it may mean that they represent a pure and noble quality or a fresh and refined style. It can break the conventional tedious and boring and bring new experiences and inspiration to the readers. For example, some novels might describe a fresh and refined character who had extraordinary wisdom and noble moral character. They would become a clear stream of the entire story, bringing inspiration and touching to the readers.
