I believe they have wings, they can fly higher than blizzard. Staying on the 59 meter tall power pylon, but they are not birds.

我相信他们是有翅膀的，他们的‘飞翔’比暴风雪更高，在59米的高塔上，他们不是栖息的鸟儿。

And why we need them... believe it or not, they are our souls, which explains why I believe people can definitely fly in their dreams.

我们为什么需要它们，也许很难相信，但是它们就是我们的灵魂。它们的存在恰好解释了我对人可以在梦里飞行的坚信。
