The Manchu bow is a type of composite recurve bow historically used in Manchuria, and subsequently spread to China, Mongolia, and Tibet during the Qing dynasty. It is similar in construction and likely shares roots with the medieval Mongol bow. It is characterized by very large siyahs, long draw length, prominent string bridges, and use with typically large and heavy arrows. Due to its extensive usage outside of Manchuria, this bow is also often also identified to as a Chinese bow or Mongol bow, and during the 17th century, it's widespread usage (along with the increasing proliferation of firearms) almost completely displaced all other types of bows in the Qing Empire.
