"The purpose in writing this book is to address the English readers who are interested in learning how to play the erhu. There are many erhu instruction books that have been published, but few, if any, in English. I fell in love with this wonderful instrument when I was twelve years old and I’d like to make learning this instrument accessible to as many people as possible!"
