Yufei goes from eagerly rocking on his heels to having a completely different perspective, if he thought going from almost eight feet tall to six feet was a wild shift - going from six feet to nine inches is even more extreme. He gives a little hop, flipping his new wings out to look at them, and almost falling over because his neck rotates a lot more than it used to.

But now the moment of truth. He gives a few flaps, not getting much lift until he gives a running start and takes off, soaring ... well not majestically, a little like a drunk pigeon, but he's enjoying himself. He glides through the air giving a happy falcon screech.

This is the best day of his life.
