The word "沉浮" is formed by directly combining the character "沉" (chén), which means to sink or submerge, with the character "浮" (fú), which means to float or rise; these two characters, representing opposite actions, are placed side-by-side to create a compound whose meaning encompasses both states, typically referring to the alternating dynamics of sinking and floating and, by extension, to fluctuations or rises and falls in circumstance.
