At the end of the film, Andy wrote a letter to Rhett after he escaped from prison, saying, "Remember, hope is a good thing, maybe the best of things, and good things never die." . Think of wang, "I was twenty-one years old that day. In the golden age of my life, I had many extravagant hopes. I want to love, I want to eat, and I want to instantly become a half-bright and half-dark cloud in the sky. Later, I learned that life is a process of being hammered slowly. People get older day by day, and expectations disappear day by day. Finally, they became like a beaten cow. " Life is like being locked in a shark castle. When discovering the essence of life, is it obedience or resistance? Sometimes you don't even know if you're in a shark castle. Salvation or not, maybe it's just an idiotic dream. In the end, Rhett is lucky and Andy is great.
