The phrase "時代的一粒灰,落在個人頭上,就是一座山 (shídài de yī lì huī, luò zài gèrén tóu shàng, jiùshì yī zuò shān)" is a Chinese saying that means a tiny piece of dust from the era, when it falls on an individual, becomes a mountain. It illustrates how significantly an era's unfavorable elements can affect an individual. Please double-check the accuracy of the statement and context if it is important.
