Is a waterfall a symbol?

Waterfalls are symbols. The waterfall falls from top to bottom under the influence of gravity. After making a roaring sound during the rapid fall, it finally forms a stream. The symbol represented by this waterfall is a metaphor for the mental state of mother and daughter. First of all, in the context of the epidemic, everyone wears a mask, and a barrier has been formed between people, creating a distance. The daughter and her mother had unpleasantness in the morning when they went to work and go to school. The economic downturn caused by the epidemic has directly affected the work of foreign trade companies. The classmates who were diagnosed forced Xiaojing and her mother to quarantine at home. This is all to gather contradictory forces for the waterfall that is about to fall.
