The ''hulusi'' was originally used primarily in the Yunnan province by the and other non-Han ethnic groups but is now played throughout China, and ''hulusi'' are manufactured in such northern cities as Tianjin. Like the related free reed pipe called bawu, the ''hulusi'' has a very pure, clarinet-like sound.
Although the ''hulusi'' is still predominantly performed in China, it has in recent years been adopted by European composers and performers. Rohan Leach from England; Rapheal De Cock from Belgium and Herman Witkam from the Netherlands have all taken the instrument in new directions.
A similar instrument called ''hulusheng'' is a mouth organ with a gourd wind chest.
The instrument's name comes from the Chinese words ''hulu'', meaning "gourd," and ''si'', meaning "silk" . The instrument is called ''bilangdao'' in the Dai language.
