There is a legend about a bird that sings only once in its life, and its song is more beautiful than the songs of all creatures in the world. From the moment he left the nest, he was looking for the thorn tree, and he didn't rest until he found what he wanted. Then, it plunged its body into the longest and sharpest thorn, and let loose its voice among the wild branches. In its dying moments, it transcended its own pain, and its song eclipsed both the lark and the nightingale. This is an extremely beautiful song, and the song ends with death. However, the whole world is still listening, and God is smiling in the sky. Because the best things can only be exchanged for the deepest pain...

Its singing is singing at the cost of life, and it is the most poignant swan song in the world. This is not only a raw attitude, but also a way of love that moves the world.

The bird has a thorn on its chest. It pursues an unchangeable law. It is pierced by an unknown thing, driven away, and dies singing. At the moment when the thorns pierced her, she didn't realize that death was coming. She just sang and sang until her life was exhausted and she could no longer sing a note. However, when we pierce the thorns into our chests, we know it, we are clear about it, but we still do it, we still pierce the thorns into our chests. ”
