Why did Karry tie him up when he sang Brave and Beautiful?

Karry's "Bound Him with Boldness and Beauty" is a design for a stage performance. At the New Year's Eve party of Jiangsu Satellite TV, Karry sang three songs in succession, from Wan Li Going Home to WeWillRockYou, and then to Boldness and Beauty. Three different styles of songs exploded on the stage in each capital. Especially when singing "Wan Li's Way Home", Karry hung Weiya in one hand and fell directly from the stage to the stage. The action was so handsome that many viewers screamed wildly at this behavior, which was really unexpected.
