supports: Flint is a hard, sedimentary cryptocrystalline form of the mineral quartz, categorized as a variety of chert. It occurs chiefly as nodules and masses in sedimentary rocks, such as chalks and limestones. Inside the nodule, flint is usually dark grey, black, green, white or brown in colour, and often has a glassy or waxy appearance. A thin layer on the outside of the nodules is usually different in colour, typically white and rough in texture. From a petrological point of view, "flint" refers specifically to the form of chert which occurs in chalk or marly limestone. Similarly, "common chert" (sometimes referred to simply as "chert") occurs in limestone. A lozenge (), often referred to as a diamond, is a form of rhombus. The definition of lozenge is not strictly fixed, and it is sometimes used simply as a synonym (from the French "losange") for rhombus. Most often, though, lozenge refers to a thin rhombusa rhombus with acute angles of less than 45°. The lozenge shape is often used in parquetry and as decoration on ceramics, silverware and textiles. It also features in heraldry and playing cards. Obsidian is a naturally occurring volcanic glass formed as an extrusive igneous rock. Wood is a porous and fibrous structural tissue found in the stems and roots of trees, and other woody plants. It is an organic material, a natural composite of cellulose fibers which are strong in tension embedded in a matrix of lignin which resists compression. Wood is sometimes defined as only the secondary xylem in the stems of trees, or it is defined more broadly to include the same type of tissue elsewhere such as in the roots of trees or shrubs. In a living tree it performs a support function, enabling woody plants to grow large or to stand up by themselves. It also conveys water and nutrients between the leaves, other growing tissues, and the roots. Wood may also refer to other plant materials with comparable properties, and to material engineered from wood, or wood chips or fiber. A pole weapon or polearm is a close combat weapon in which the main fighting part of the weapon is fitted to the end of a long shaft, typically of wood, thereby extending the user's effective range. Glaives, poleaxes, halberds, and naginata are all varieties of polearms. Steel is an alloy of iron and other elements, primarily carbon, that is widely used in construction and other applications because of its high tensile strength and low cost. Steel's base metal is iron, which is able to take on two crystalline forms (allotropic forms), body centered cubic and face centered cubic (FCC), depending on its temperature. It is the interaction of those allotropes with the alloying elements, primarily carbon, that gives steel and cast iron their range of unique properties. In the body-centred cubic arrangement, there is an iron atom in the centre of each cube, and in the face-centred cubic, there is one at the center of each of the six faces of the cube. Carbon, other elements, and inclusions within iron act as hardening agents that prevent the movement of dislocations that otherwise occur in the crystal lattices of iron atoms. A spear is a pole weapon consisting of a shaft, usually of wood, with a pointed head. The head may be simply the sharpened end of the shaft itself, as is the case with fire hardened spears, or it may be made of a more durable material fastened to the shaft, such as flint, obsidian, iron, steel or bronze. The most common design for hunting or combat spears since ancient times has incorporated a metal spearhead shaped like a triangle, lozenge, or leaf. The heads of fishing spears usually feature barbs or serrated edges. Yue (Old Chinese: "*"), also known as Yuyue, was a state in ancient China which existed during the first millennium BC the Spring and Autumn and Warring States periods of China's Zhou dynasty in the modern provinces of Zhejiang, Shanghai, and Jiangsu. Its original capital was a site near Mount Kuaiji (around modern Shaoxing); after its conquest of Wu, the Kings of Yue moved their court north to the city of Wu (modern Suzhou). Iron is a chemical element with symbol Fe (from ) and atomic number 26. It is a metal in the first transition series. It is by mass the most common element on Earth, forming much of Earth's outer and inner core. It is the fourth most common element in the Earth's crust. Its abundance in rocky planets like Earth is due to its abundant production by fusion in high-mass stars, where it is the last element to be produced with release of energy before the violent collapse of a supernova, which scatters the iron into space. Bronze is an alloy consisting primarily of copper, commonly with about 12% tin and often with the addition of other metals (such as aluminium, manganese, nickel or zinc) and sometimes non-metals or metalloids such as arsenic, phosphorus or silicon. These additions produce a range of alloys that may be harder than copper alone, or have other useful properties, such as stiffness, ductility, or machinability. The Spear of Fuchai (  ) is purportedly the spear of King Fuchai of Wu , the arch - rival of King Goujian of Yue . It was unearthed in Jiangling , Hubei in November 1983 . The script on it is a kind of script used only in the states of Wu , Yue ( state ) , and Chu called  or bird and worms script , a variant of seal script . The inscription mirrors the text of King Goujian 's Sword , except changing the name of the owner and the type of weapon . In this case , the text reads , ``  '' or `` ( Belonging to ) King Fuchai of Wu made for his personal use , this spear . '' Old Chinese, also called Archaic Chinese in older works, is the oldest attested stage of Chinese, and the ancestor of all modern varieties of Chinese.
  The earliest examples of Chinese are divinatory inscriptions on oracle bones from around 1250 BC, in the late Shang dynasty.
  Bronze inscriptions became plentiful during the following Zhou dynasty.
  The latter part of the Zhou period saw a flowering of literature, including classical works such as the "Analects", the "Mencius", and the "Zuozhuan".
  These works served as models for Literary Chinese (or Classical Chinese), which remained the written standard until the early twentieth century, thus preserving the vocabulary and grammar of late Old Chinese.
