Two-in-One! Erhu Cover Introducing a two-in-one erhu cover that you didn't know you needed! When storing an erhu, many people use erhu covers or cloth to prevent rosin from the bow hair from sticking to the strings and to prevent the bow hair from getting caught on the fine tuner adjusters. This erhu cover has been given another function!
