The Vietnamese word "phù trầm" can be understood as "full of ups and downs" or "full of vicissitudes." It describes a situation, life, or experience that is characterized by many changes, challenges, and fluctuations, often reflecting a sense of unpredictability.
While "phù trầm" primarily conveys the idea of ups and downs, it can also imply a sense of struggle or hardship, suggesting that the journey has not always been easy.
