I wonder why the obvious solution hasn't occurred to them. Let Shaoying sing at one of their venues. They have gambling dens, restuarants, clubs, already. Doesn't take much to put up a stage. It's not the same scale as Fairyland, but it lets her work and feel like she's contributing.
In other news, zero percent chance the angry guy who just stormed out won't go causing trouble and spreading rumors. Might even run to a competitor to sell Yan Chu out. They should have dealt with him then and there.
