"问题不在于为朋友去死，而在于找到一个值得为之死的朋友。"

Simplified Meaning:

Finding a true friend is more difficult than being willing to make a great sacrifice for one. Many people might feel that they could give up a lot or even everything for someone they care about, but the hard part is locating that one special person who is truly worth it. Imagine during a tough time in your life, many people might offer to help, but only a real friend will be there for you without expecting anything in return. For instance, in history, soldiers have often formed bonds so strong that they would risk their lives for each other. In everyday life, a true friend is someone who stands with you through thick and thin, supports you without judgment, and values your happiness as their own. By focusing on building deep, genuine connections, you can eventually find a friend who is truly deserving of your profound loyalty and sacrifice.
