"Blind" Ābǐng was a blind Chinese musician specializing in the erhu and pipa. Abing's most famous piece is entitled Erquan Yingyue (二泉映月), which is named after a spring in Wuxi (which is today part of Xihui Park). It is still played as a standard erhu piece, although it necessitates a special set of strings that are tuned lower than normal erhu strings.
