Searches on Craigslist turned up no ads for erhus, wanted or offered, though there was a posting for an instrument found on the Lower East Side (the owner must identify the instrument).
Baritone Qu Yue sings of the sinking Red Regime, Xiaochun Qi performs an erhu piece titled Saving the Predestined.
The hardingfele, rebec, kokyu, igil, nyckelharpa and erhu are also some of the commonly known string instruments played by bowing.
The production features instrumental performances, including a soloist playing the erhu, a stringed Chinese instrument.
