When I was a child, I often set foot on mountain paths and forest collection sites with my friends. Birds are singing beautiful songs freely, and we are enjoying infinite interest and fun in the embrace of nature.

But in the mountain village of my hometown, the Huangling bird disappeared without a trace, and there was no such scene as when I was a child. There are fewer and fewer forests, and the living space of birds is getting narrower and narrower, which makes them suffocate. The unprecedented destruction of forests by human beings makes birds hide in dark corners like wolves in the wilderness when they are injured and worry about the status quo. Therefore, we should think rationally.
