"鸟儿歌唱不是因为它有答案，而是因为它有歌。"

Simplified Meaning:

This quote is saying that sometimes, people do things just because it's part of who they are, not because they are trying to solve a problem or give a solution. Like how a bird sings not because it knows something, but because singing is natural to it. For example, think about a person who loves to paint pictures. They don't paint because they have to fix or explain something. They paint because it makes them happy and it's part of what they love. Similarly, in your own life, you can take joy in doing things that you love, even if they don't have a specific purpose or answer a question. Just as the bird sings its song because that's what it does, you can find happiness in your hobbies and passions without needing to have a reason or outcome. This allows you to appreciate the beauty and joy in everyday actions. So, enjoy what you do and let it be a natural expression of who you are, just because it feels right and makes you happy.
