China has been the source of many innovations, scientific discoveries and inventions. Below is an alphabetical list of inventions and discoveries made by Neolithic cultures of China and those of its prehistorical early Bronze Age before the palatial civilization of the Shang dynasty (c. 1650 – c. 1050 BC). These include the Bronze Age Erlitou culture and the semi-legendary Xia dynasty that, unlike the Shang, is not yet confirmed to have existed with evidence of contemporary texts. The contemporaneous Peiligang and Pengtoushan cultures represent the oldest Neolithic cultures of China and were formed around 7000 BC. Some of the first inventions of Neolithic China include semilunar and rectangular stone knives, stone hoes and spades, the cultivation of millet and the soybean, the refinement of sericulture, rice cultivation, the creation of pottery with cord-mat-basket designs, the creation of pottery vessels and pottery steamers and the development of ceremonial vessels and scapulimancy for purposes of divination. The British sinologist Francesca Bray argues that the domestication of the ox and buffalo during the Longshan culture (c. 3000 – c. 2000 BC) period, the absence of Longshan-era irrigation or high-yield crops, full evidence of Longshan cultivation of dry-land cereal crops which gave high yields "only when the soil was carefully cultivated," suggest that the plow was known at least by the Longshan culture period and explains the high agricultural production yields which allowed the rise of Chinese civilization during the Shang dynasty. Later inventions such as the multiple-tube seed drill and the heavy moldboard iron plow enabled China to sustain a much larger population through greater improvements in agricultural output.
Inventions and discoveries Bell: Clapper-bells made of pottery have been found in several archaeological sites. The earliest metal bells, with one found in the Taosi site, and four in the Erlitou site, dated to about 2000 BC, may have been derived from the earlier pottery prototype. Early bells not only have an important role in generating metal sound, but arguably played a prominent cultural role. With the emergence of other kinds of bells during the Shang dynasty (c. 1600 – c. 1050 BC), they were relegated to subservient functions; at Shang and Zhou sites, they are also found as part of the horse-and-chariot gear and as collar-bells of dogs. Coffin, wooden: The earliest evidence of wooden coffin remains, dated at 5000 BC, was found in the Tomb 4 at Beishouling, Shaanxi. Clear evidence of a wooden coffin in the form of a rectangular shape was found in Tomb 152 in an early Banpo site. The Banpo coffin belongs to a four-year-old girl, measuring 1.4 m (4.5 ft) by 0.55 m (1.8 ft) and 3–9 cm thick. As many as 10 wooden coffins have been found from the Dawenkou culture (4100–2600 BC) site at Chengzi, Shandong. The thickness of the coffin, as determined by the number of timber frames in its composition, also emphasized the level of nobility, as mentioned in the Classic of Rites, Xunzi and Zhuangzi. Examples of this have been found in several Neolithic sites; the double coffin, the earliest of which was found in the Liangzhu culture (3400–2250 BC) site at Puanqiao, Zhejiang, consists of an outer and an inner coffin, while the triple coffin, with its earliest finds from the Longshan culture (3000–2000 BC) sites at Xizhufeng and Yinjiacheng in Shandong, consists of two outer and one inner coffins. Cookware and pottery vessel: The earliest known pottery vessels, dating to 20,000 to 19,000 BP, were excavated in Xianrendong Cave located in the Jiangxi province of China. The presence of scorched surfaces on the pot shards indicates that they were likely used as cookware. An excavation of Yuchanyan Cave in Hunan province found pottery dating to 18,300 to 15,430 BP. The manufacture of pottery by hunter-gatherers in East Asia predates the emergence of agriculture in that region by 10,000 years, challenging the traditionally held belief that pottery resulted from the Neolithic Revolution.
Dagger-axe: The dagger-axe or ge was developed from agricultural stone implement during the Neolithic, dagger-axe made of stone are found in the Longshan culture (3000–2000 BC) site at Miaodian, Henan. It also appeared as ceremonial and symbolic jade weapon at around the same time, two being dated from about 2500 BC, are found at the Lingjiatan site in Anhui. The first bronze ge appeared at the early Bronze Age Erlitou site, where two were being found among the over 200 bronze artifacts (as of 2002) at the site, three jade ge were also discovered from the same site. Total of 72 bronze ge in Tomb 1004 at Houjiazhuang, Anyang, 39 jade ge in tomb of Fu Hao and over 50 jade ge at Jinsha site were found alone. It was the basic weapon of Shang (c. 1600 – 1050 BC) and Zhou (c.1050–256 BC) infantry, although it was sometimes used by the "striker" of charioteer crews. It consisted of a long wooden shaft with a bronze knife blade attached at a right angle to the end. The weapon could be swung down or inward in order to hook or slash, respectively, at an enemy. By the early Han dynasty (202 BC – 220 AD), military use of the bronze ge had become limited (mostly ceremonial); they were slowly phased out during the Han dynasty by iron spears and iron ji halberds. Deepwater drilling: Some of the earliest evidence of water wells are located in China. The Chinese discovered and made extensive use of deep drilled groundwater for drinking. The Chinese text The Book of Changes, originally a divination text of the Western Zhou dynasty (1046 -771 BC), contains an entry describing how the ancient Chinese maintained their wells and protected their sources of water. Archaeological evidence and old Chinese documents reveal that the prehistoric and ancient Chinese had the aptitude and skills for digging deep water wells for drinking water as early as 6000 to 7000 years ago. A well excavated at the Hemudu excavation site was believed to have been built during the Neolithic era. The well was cased by four rows of logs with a square frame attached to them at the top of the well. 60 additional tile wells southwest of Beijing are also believed to have been built around 600 BC for drinking and irrigation.
