"The hulusi (traditional: \u846B\u8606\u7D72; simplified: \u846B\u82A6\u4E1D; pinyin: h\u00FAl\u00FAs\u012B) or cucurbit flute is a free reed wind instrument from China. It is held vertically and has three bamboo pipes which pass through a gourd wind chest; the center pipe has finger holes and the outer two are typically drone pipes. It is not uncommon for a hulusi to have only one drone pipe while the second outer pipe is merely ornamental. The drone pipe has a finger hole, which allows it to be stopped."@en . . .
