"我们必须自由，不是因为我们声称自由，而是因为我们实践自由。"

Simplified Meaning:

Freedom isn't just something we say we have; it's something we actually do. Imagine someone who constantly talks about being a great cook but never steps into the kitchen. They can't really say they're a great cook unless they actually make meals and show their cooking skills. Likewise, for a person or a country to truly be free, they need to live and make choices that demonstrate their freedom. For example, in history, the civil rights movement in the 1960s wasn't just about people saying they deserved equality. They marched, protested, and fought for their rights. They showed they were free by demanding and creating change. In everyday life, practicing freedom means making decisions for yourself, expressing your opinions, and standing up for what you believe in. If you want to feel free, you need to act like it—through study, voting, speaking out, and living your life fully. Freedom is a verb; it's something we must do, not just talk about.
