牛人！轮子推动大号！键钮改为键板超常吹奏！

初见大号 以为是广场上的音乐雕塑，二见大号四轮跑以为是个音乐玩具，再见大号台上的演奏 ，小伙伴们惊呆了！是真的吗？

When I saw the big size, I thought it was the music sculpture of the square. I saw the two size and four rounds. I thought it was a musical toy. I saw the big stage playing, and my little friends were shocked! Is that true?
