Erhu

I bought the Erhu recently.
I don't know how to play it and I don't know anything about it! But I bought it.:)
Because, I was fascinated by the sound of erhu when I returned to my hometown Okinawa last year. My heart has been healed to the sound of it.
I am always playing Sanshin , but I cannot play the erhu, so I have to go to school...
