What is "muyesinbo"

The Muyesinbo (or Muyeshinbo, meaning "new compendium of martial arts") is a Korean martial arts manual published in 1759. The book is a revision of the older Muyejebo, made during the reign of King Youngjo (1724–1776). It adds twelve disciplines or "skills" of both armed and unarmed fighting by Prince Sado to the original six which were descbribed in the Muyejebo. No copies of the Muyesinbo have survived, but its contents can easily be determined by tracing back and comparing the Muyejebo with the later Muyedobotongji.

Prince Sado also originated the term Sib Pal Gi (십팔기, 十八技, “Eighteen [Fighting] Methods” or possibly "Eighteen [Warrior's] Tools” if using 十八器), shortened from Bonjo Muye Sib Pal Ban (본조무예십팔반, 本條武藝十八般, "A Treatise on the 18 Martial Categories of the Yi Dynasty"). This mirrors the Chinese concept of the " Eighteen Arms of Wushu" to identify the Korean collection of weapons depicted in the Mu Ye Sin Bo (note that 十八般兵器 is pronounced Sip Pal Ban Byeong Gi in Korean, 십팔반병기, where the words Ban Byeong are left out to render Prince Sado's term, and these omitted words roughly translate as "martial methods" making them essentially superfluous when taken in context).
