The title of the book is "There are two types of the pre-Qin bow - the self-bow and the composite bow. All except one of the fifty-five bows from Marquis Yi's tomb are made up of three wooden pieces joined together with short pieces fastened to it. There are bent parts made of horns at both ends, with clearly visible string grooves. Also unearthed are 4,507 bronze arrows in a variety of shapes. Many of them have three or six bows, or even nine bows. An arrow consists of two parts - arrowhead and shaft. The arrows are made from bamboo. The total lengths of the arrows range from 67cm to 71cm. At the time of unearthing, some of the bows have intact shafts. They were tied up in bundles with fifty arrows in each.
