Changsha
–
Changsha is the capital of Hunan province, south central China. It covers 11,819 km2 and is bordered by Yueyang and Yiyang to the north, Loudi to the west, Xiangtan and Zhuzhou to the south, Yichun and Pingxiang of Jiangxi province to the east. According to 2010 Census, Changsha has 7,044,118 residents and it has a moist monsoon climate of the subtropical zone. The average annual air temperature is 16. 8–17.3 °C, Changsha is famous for that it was the capital of Changsha State in the Han Dynasty, and the capital of Chu State in Ten Kingdoms period. The lacquerware and Silk Texts recovered from Mawangdui there are an indication of the richness of local craft traditions, in 1904, Changsha was opened to foreign trade, and large numbers of Europeans and Americans settled there. Changsha was the site of Mao Zedongs conversion to communism and it was also the scene of major battles in the Sino-Japanese War and was briefly occupied by the Japanese. Nowadays, Changsha is an important commercial, manufacturing and transportation center in China, the origins of the name Changsha are lost in antiquity. In the 2nd century AD, historian Ying Shao wrote that the Qin dynasty use of the name Changsha for the area was a continuance of its old name, archeologial evidence provides evidence of settlement 150,000 to 200,000 BC. Development occurred drastically closer to 3000BC when Changsha developed with the proliferation of Longshan culture, despite this, pottery and bronze ware have been discovered. In the Central Plain region during the Zhou and Shang dynasties, Sima Qian writes in his Records of the Grand Historian Huangdi, loving his Shaohao, gave him a parcel of land, an area amounted to Changsha and surrounding land. Evidence exists that people lived and thrived in the area during the Bronze Age, numerous examples of pottery and items of interest were discovered and recovered. Changsha entered a time of turmoil, eastern Zhous collapse swept in turmoil with the Spring and Autumn Period. The Yue culture spread and took a stronghold through the region, during the height of the Warring States Period, the Chu Kingdom took a hardline nationalist and reform approach and took a large-scale military operations in South China. Chu Kingdom took control of Changsha and turned the city into an important part of the part of Chu. After years of war and occupation, Changsha slowly replaced Yue culture with Chu culture, nobles created tombs and got buried in tombs. In 1951-1957, archaeologists explored numerous large and medium-sized Chu tombs from the warring states era, there have been more than 3,000 tombs discovered of various people. The coming of Chu brought a lot of tools and production experience, massive changes quickly propelled Changsha through the Iron Age and into the feudal age of society. The city is sometimes called Qingyang in Warring States period texts, the slow wearing of time, turbulence, and turmoil weakened the Changsha and the region

China
–
China, officially the Peoples Republic of China, is a unitary sovereign state in East Asia and the worlds most populous country, with a population of over 1.381 billion. The state is governed by the Communist Party of China and its capital is Beijing, the countrys major urban areas include Shanghai, Guangzhou, Beijing, Chongqing, Shenzhen, Tianjin and Hong Kong. China is a power and a major regional power within Asia. Chinas landscape is vast and diverse, ranging from forest steppes, the Himalaya, Karakoram, Pamir and Tian Shan mountain ranges separate China from much of South and Central Asia. The Yangtze and Yellow Rivers, the third and sixth longest in the world, respectively, Chinas coastline along the Pacific Ocean is 14,500 kilometers long and is bounded by the Bohai, Yellow, East China and South China seas. China emerged as one of the worlds earliest civilizations in the basin of the Yellow River in the North China Plain. For millennia, Chinas political system was based on hereditary monarchies known as dynasties, in 1912, the Republic of China replaced the last dynasty and ruled the Chinese mainland until 1949, when it was defeated by the communist Peoples Liberation Army in the Chinese Civil War. The Communist Party established the Peoples Republic of China in Beijing on 1 October 1949, both the ROC and PRC continue to claim to be the legitimate government of all China, though the latter has more recognition in the world and controls more territory. China had the largest economy in the world for much of the last two years, during which it has seen cycles of prosperity and decline. Since the introduction of reforms in 1978, China has become one of the worlds fastest-growing major economies. As of 2016, it is the worlds second-largest economy by nominal GDP, China is also the worlds largest exporter and second-largest importer of goods. China is a nuclear weapons state and has the worlds largest standing army. The PRC is a member of the United Nations, as it replaced the ROC as a permanent member of the U. N. Security Council in 1971. China is also a member of numerous formal and informal multilateral organizations, including the WTO, APEC, BRICS, the Shanghai Cooperation Organization, the BCIM, the English name China is first attested in Richard Edens 1555 translation of the 1516 journal of the Portuguese explorer Duarte Barbosa. The demonym, that is, the name for the people, Portuguese China is thought to derive from Persian Chīn, and perhaps ultimately from Sanskrit Cīna. Cīna was first used in early Hindu scripture, including the Mahābhārata, there are, however, other suggestions for the derivation of China. The official name of the state is the Peoples Republic of China. The shorter form is China Zhōngguó, from zhōng and guó and it was then applied to the area around Luoyi during the Eastern Zhou and then to Chinas Central Plain before being used as an occasional synonym for the state under the Qing

Han dynasty
–
The Han dynasty was the second imperial dynasty of China, preceded by the Qin dynasty and succeeded by the Three Kingdoms period. Spanning over four centuries, the Han period is considered an age in Chinese history. To this day, Chinas majority ethnic group refers to itself as the Han people and it was founded by the rebel leader Liu Bang, known posthumously as Emperor Gaozu of Han, and briefly interrupted by the Xin dynasty of the former regent Wang Mang. This interregnum separates the Han dynasty into two periods, the Western Han or Former Han and the Eastern Han or Later Han, the emperor was at the pinnacle of Han society. He presided over the Han government but shared power with both the nobility and appointed ministers who came largely from the gentry class. The Han Empire was divided into areas controlled by the central government using an innovation inherited from the Qin known as commanderies. These kingdoms gradually lost all vestiges of their independence, particularly following the Rebellion of the Seven States, from the reign of Emperor Wu onward, the Chinese court officially sponsored Confucianism in education and court politics, synthesized with the cosmology of later scholars such as Dong Zhongshu. This policy endured until the fall of the Qing dynasty in 1911 AD, the Han dynasty was an age of economic prosperity and saw a significant growth of the money economy first established during the Zhou dynasty. The coinage issued by the government mint in 119 BC remained the standard coinage of China until the Tang dynasty. The period saw a number of limited institutional innovations, the Xiongnu, a nomadic steppe confederation, defeated the Han in 200 BC and forced the Han to submit as a de facto inferior partner, but continued their raids on the Han borders. Emperor Wu of Han launched several campaigns against them. The ultimate Han victory in these wars eventually forced the Xiongnu to accept vassal status as Han tributaries, the territories north of Hans borders were quickly overrun by the nomadic Xianbei confederation. Imperial authority was seriously challenged by large Daoist religious societies which instigated the Yellow Turban Rebellion. When Cao Pi, King of Wei, usurped the throne from Emperor Xian, following Liu Bangs victory in the Chu–Han Contention, the resulting Han dynasty was named after the Hanzhong fief. Chinas first imperial dynasty was the Qin dynasty, the Qin unified the Chinese Warring States by conquest, but their empire became unstable after the death of the first emperor Qin Shi Huangdi. Within four years, the authority had collapsed in the face of rebellion. Although Xiang Yu proved to be a commander, Liu Bang defeated him at Battle of Gaixia. Liu Bang assumed the title emperor at the urging of his followers and is known posthumously as Emperor Gaozu, Changan was chosen as the new capital of the reunified empire under Han

Five Dynasties and Ten Kingdoms period
–
The Five Dynasties and Ten Kingdoms period, also called Five Dynasties, was an era of political upheaval in 10th-century imperial China. During this period, five states quickly succeeded one another in the Chinese Central Plain, while more than a dozen concurrent states were established elsewhere, mainly in south China. Traditionally, the era started with the fall of the Tang dynasty in 907 AD, many states were de facto independent kingdoms long before 907. After the Tang had collapsed, the kings who controlled the central plain crowned themselves as emperor, war between kingdoms occurred frequently to gain control of the central plain for legitimacy, and then over whole China. The last of the Five Dynasties and Ten Kingdoms states, Northern Han, was not vanquished until 979, the Five Dynasties were, Later Liang Later Tang Later Jin Later Han Later Zhou. The Ten Kingdoms were, Wu Wuyue Min Chu Southern Han Former Shu Later Shu Jingnan Southern Tang Northern Han and this era also led to the founding of the Liao dynasty in the north. Other regimes during this period were Yan, Qi, Zhao, Yiwu Jiedushi, Dingnan Jiedushi, Wuping Jiedushi, Qingyuan Jiedushi, Yin, Ganzhou, Shazhou, towards the end of the Tang, the imperial government granted increased powers to the jiedushi, the regional military governors. The Huang Chao Rebellion weakened the government, and by the early 10th century the jiedushi commanded de facto independence from its authority. Thus ensued the Five Dynasties and Ten Kingdoms period, although he was originally a member of Huang Chaos rebel army, he took on a crucial role in suppressing the Huang Chao Rebellion. For this function, he was awarded the Xuanwu Jiedushi title, within a few years, he had consolidated his power by destroying neighbours and forcing the move of the imperial capital to Luoyang, which was within his region of influence. In 904, he executed Emperor Zhaozong of Tang and made his 13-year-old son a subordinate ruler, three years later, he induced the boy emperor to abdicate in his favour. He then proclaimed emperor, thus beginning the Later Liang. During the final years of the Tang Dynasty, rival warlords declared independence in their governing provinces — not all of whom recognized the emperors authority, Li Cunxu and Liu Shouguang fiercely fought the regime forces to conquer northern China, Li Cunxu succeeded. He defeated Liu Shouguang in 915, and declared himself emperor in 923, within a few months, thus began the Shatuo Later Tang — the first in a long line of conquest dynasties. After reuniting much of northern China, Cunxu conquered Former Shu in 925, the Later Tang had a few years of relative calm, followed by unrest. In 934, Sichuan again asserted independence, in 936, Shi Jingtang, a Shatuo jiedushi from Taiyuan, was aided by the Liao dynasty in a rebellion against the Later Tang. In return for their aid, Shi Jingtang promised annual tribute, the rebellion succeeded, Shi Jingtang became emperor in this same year. Not long after the founding of the Later Jin, the Khitans regarded the emperor as a ruler for China proper

Charcoal
–
Charcoal is a lightweight, black residue, consisting of carbon and any remaining ash, obtained by removing water and other volatile constituents from animal and vegetation substances. Charcoal is usually produced by slow pyrolysis- the heating of wood or other substances in the absence of oxygen, the whole pile is covered with turf or moistened clay. The firing is begun at the bottom of the flue, the success of the operation depends upon the rate of the combustion. The operation is so delicate that it was left to colliers. They often lived alone in small huts in order to tend their wood piles, for example, in the Harz Mountains of Germany, charcoal burners lived in conical huts called Köten which are still much in evidence today. The massive production of charcoal was a cause of deforestation. The increasing scarcity of easily harvested wood was a factor behind the switch to fossil fuel equivalents, mainly coal. Charcoal made at 300 °C is brown, soft and friable, and readily inflames at 380 °C, made at higher temperatures it is hard and brittle, in Finland and Scandinavia, the charcoal was considered the by-product of wood tar production. The best tar came from pine, thus pinewoods were cut down for tar pyrolysis, the residual charcoal was widely used as substitute for metallurgical coke in blast furnaces for smelting. Tar production led to deforestation, it has been estimated all Finnish forests are younger than 300 years. The end of tar production at the end of the 19th century resulted in rapid re-forestation, the charcoal briquette was first invented and patented by Ellsworth B. A. Zwoyer of Pennsylvania in 1897 and was produced by the Zwoyer Fuel Company. The process was popularized by Henry Ford, who used wood. Ford Charcoal went on to become the Kingsford Company, Charcoal has been made by various methods. The traditional method in Britain used a clamp and this is essentially a pile of wooden logs leaning against a chimney. The chimney consists of 4 wooden stakes held up by some rope, the logs are completely covered with soil and straw allowing no air to enter. It must be lit by introducing some burning fuel into the chimney, if the soil covering gets torn by the fire, additional soil is placed on the cracks. Once the burn is complete, the chimney is plugged to prevent air from entering, the true art of this production method is in managing the sufficient generation of heat, and its transfer to wood parts in the process of being carbonised. A strong disadvantage of this method is the huge amount of emissions that are harmful to human health

Lacquer
–
The term lacquer is used for a number of hard and potentially shiny finishes applied to materials such as wood. These fall into a number of different groups. This dries to a hard and smooth surface layer which is durable, waterproof. Asian lacquer is sometimes painted with pictures, inlaid with shell and other materials, or carved, as well as dusted with gold and given other further decorative treatments. In modern techniques, lacquer means a range of clear or coloured wood finishes that dry by solvent evaporation or a process that produces a hard. The finish can be of any level from ultra matte to high gloss. It is also used for paint, which is a paint that typically dries better on a hard. Lacquer is more durable than shellac and these ultimately derive from Sanskrit lākshā, which was used for both the Lac insect and the scarlet resinous secretion it produces that was used as wood finish. Lac resin was once imported in quantity into Europe from India along with Eastern woods. Lacquer sheen is a measurement of the shine for a given lacquer, different manufacturers have their own names and standards for their sheen. The most common names from least shiny to most shiny are, flat, matte, egg shell, satin, semi-gloss, urushiol-based lacquers differ from most others, being slow-drying, and set by oxidation and polymerization, rather than by evaporation alone. In order for it to set properly it requires a humid, the phenols oxidize and polymerize under the action of an enzyme laccase, yielding a substrate that, upon proper evaporation of its water content, is hard. These lacquers produce very hard, durable finishes that are beautiful and very resistant to damage by water, acid, alkali or abrasion. The active ingredient of the resin is urushiol, a mixture of various phenols suspended in water, the resin is derived from a tree indigenous to China, species Toxicodendron vernicifluum, commonly known as the Lacquer Tree. The fresh resin from the T. vernicifluum trees causes urushiol-induced contact dermatitis, the Chinese treated the allergic reaction with crushed shellfish, which supposedly prevents lacquer from drying properly. Lacquer skills became very highly developed in Asia, and many highly decorated pieces were produced, the earliest extant lacquer object, a red wooden bowl, was unearthed at a Hemudu culture site in China. By the Han Dynasty, many centres of production became firmly established. The knowledge of the Chinese methods of the process spread from China during the Han, Tang and Song dynasties, eventually it was introduced to Korea, Japan, Southeast
