Neolithic signs in China
Since the second half of the 20th century, inscriptions have been found on pottery in a variety of locations in China, such as Banpo near Xi'an, as well as on bone and bone marrows at Hualouzi, Chang'an County near Xi'an. These simple, often geometric, marks have been frequently compared to some of the earliest known Chinese characters appearing on the oracle bones, and some have taken them to mean that the history of Chinese writing extends back over six millennia. However, only isolated instances of these symbols have been found, and they show no indication of representing speech or of the non-pictorial processes that a writing system requires.
Nature of the symbols
At a range of Neolithic sites in China, small numbers of symbols of either pictorial or simple geometric nature[a] have been unearthed which were incised into or drawn or painted on artifacts, mostly on pottery but in some instances on turtle shells, animal bones or artifacts made from bone or jade. These sites include those pertaining to the cultures of Yangshao, Liangzhu, Majiayao and Longshan.
The question of whether such symbols are writing, primitive or proto-writing, or merely non-writing symbols[b] or signs for other purposes such as identification is a highly controversial one, and the debate still continues today. Proponents of the view that they are early Chinese writing tend to see evidence in comparisons of individual signs with individual oracle bone script characters. Others believe that Neolithic signs are part of an incipient semiotic system that eventually led to the development of mature Chinese writing.
William G. Boltz of the University of Washington's Department of Asian Languages and Literature points out that such comparisons are "notoriously risky and inconclusive" when based on such primitive scratch marks rather than on similarity in function (2003, p. 38). Boltz adds:
"There does not seem to be any meaningful order of repetition or concatenation that would lead us to suspect anything more than that these are random and largely unorganized, unsystematic markings."— p.35
In general, the Neolithic symbols which have been unearthed to date are found in isolated use (as would be expected with ownership marks or clan symbols) rather than in sequences consistent with representation of the spoken language, and there is no evidence of processes fundamental to the beginnings of a true, useful writing system such as phonetic loan usage. As Qiu (2000, p. 39) explains:
Only when symbols...are consciously used to record words used to form sentences is there a true sign that the development of script has begun.
Furthermore, the evidence is still extremely scanty, even when the early Shang period evidence is added to the picture:
While these materials are very valuable, they are unfortunately few in number and most of them are rather fragmentary so that they are far from being able to provide an ample basis for solving the problem of the formation of Chinese writing.— Qiu 2000, pp.29–30
It is still safe to conclude that the earliest known undisputed examples of true writing in China (that is, symbols used to fully record language rather than isolated meanings) are the oracle bones of the late Shang dynasty, c. 1200 BCE.[c]
Jiahu is a Neolithic site in Wuyang County, Henan Province, in the basin of the Yellow River, dated to 6600–6200 BCE. This site has yielded turtle plastrons that were pitted and inscribed with markings known as the Jiahu symbols. Despite headlines proclaiming the earliest known "writing", some scholars warn that the meaningful use of such individual signs should not be easily equated with writing, although it may represent an earlier, formative stage. In the words of the archaeologists who made the latest Jiahu discovery:
"We interpret these signs not as writing itself, but as features of a lengthy period of sign-use which led eventually to a fully-fledged system of writing...The present state of the archaeological record in China, which has never had the intensive archaeological examination of, for example, Egypt or Greece, does not permit us to say exactly in which period of the Neolithic the Chinese invented their writing. What did persist through these long periods was the idea of sign use. Although it is impossible at this point to trace any direct connection from the Jiahu signs to the Yinxu[d] characters, we do propose that slow, culture-linked evolutionary processes, adopting the idea of sign use, took place in diverse settings around the Yellow River. We should not assume that there was a single path or pace for the development of a script."— Li Xueqin et al., 2003
Furthermore, there is no evidence of a direct cultural link between Jiahu and the Shang culture, and the five-millennium gap between the two makes connections unlikely; as oracle bone scholar David Keightley told the BBC:
"There is a gap of about 5,000 years. It seems astonishing that they would be connected, [...] We can't call it writing until we have more evidence."
Dadiwan (5800–5400 BCE) is a Neolithic site discovered in Qin'an County, in the province of Gansu. Its earliest phase has yielded symbols painted on the inside surfaces of pottery basins. More recent excavations there have also uncovered a handful of Neolithic symbols.
In Damaidi, at Beishan Mountain in Ningxia, 3,172 cliff carvings dating to 6000–5000 BCE have been discovered over an area of 15 square kilometers, including a reported 8,453 different kinds of pictures like celestial bodies, gods and hunting or grazing scenes. These are reputed to be similar to some of the oracle bone characters, which is to be expected given that the oracle bones, which are true writing, still retain a significant pictorial flavor.
Banpo and Jiangzhai
Another group of early symbols which many have compared to Chinese characters is the Banpo symbols from sites like Banpo, just east of Xi'an in Shaanxi province, dating from the 5th millennium BCE,[e] and nearby, at Jiangzhai, in Lintong County, from the early 4th millennium BCE. As the Banpo symbols were discovered fairly early (1954–57) and are relatively numerous (with 22 different symbols on 113 potsherds), these have been the focus of the most attention.
Some scholars have concluded that they are meaningful symbols like clan emblems or signatures which have some of the quality of writing, perhaps being primitive characters, while others have concluded based on comparisons to oracle bone script that some of them are numerals. Still others feel they may be ownership or potters' marks.
Finally, some scholars sound a note of caution, calling such conclusions unwarranted or premature. This is because all the Banpo-type symbols occur singly, on pottery and pottery fragments, unlike written words, which tend to occur in strings representing language. Thus, there is no context from which to conclude that the symbols are actually being used to represent language.
Thus, leading scholar Qiu Xigui (2000) argues that:
"What these symbols represent definitely cannot be a fully formed system of writing; this much is quite clear. Is there any possibility that they are primitive writing? Most likely there is not. We simply possess no basis for saying that they were already being used to record language. Nor viewed from the standpoint of the symbols of this same type that continued to be used following the creation of Chinese script do they even resemble script".(p.31)
"Quite a number of people, basing themselves on the Banpo-type symbols, have said that the history of Chinese writing goes back more than 6,000 years. Such claims are probably unjustified". (p.33)
In Qiu's opinion, they instead more closely resemble the non-writing symbols which remained in use even into the early historical period. Another problem which has been noted is that, since the oracle bone script was fairly pictorial in nature, if one were to go back to ancestors predating them by over three millennia, one should expect an increase in the pictorial nature of the symbols, but in fact, a comparison of the majority of the Banpo symbols shows the exact opposite to be true.
However, it is possible that some of the Banpo or other Neolithic symbols were used as numerals in a pre-literate setting. It is also plausible that when writing eventually did emerge, some such Neolithic symbols already in use (and not necessarily from such an early site as Banpo) were absorbed into that writing system.
Inscription-bearing artifacts from the Dawenkou culture in Shandong, dating to c. 2800–2500 BCE, have also been unearthed since excavations started in the 1950s, and have drawn a great deal of interest amongst researchers, in part because the Dawenkou culture is believed to be directly ancestral to the Longshan culture, which in turn is thought ancestral to the Shang, where the first undisputed Chinese writing appears. At a Dawenkou site in Shandong, one pictorial symbol has been found painted in cinnabar, while at the Dawenkou sites by the Língyáng River (陵陽河) and in Dàzhū Village (大朱村), eighteen isolated pictorial symbols of eight types incised and/or painted with cinnabar on sixteen pottery jars and shards have been found, mostly from wealthier tombs. Some resemble axes, and another has been variously described as resembling the sun above a cloud or fire , while a third type has the latter above a fire or mountain-like element.
In addition to the similarity in style between these and pictographic Shang and early Zhou clan symbols, what is important about the latter two types is that they have multiple components, reminiscent of the compounding of elements in the Chinese script, thus eliciting claims of a relationship. Yu Xingwu identified the circle-and-cloud graph as the Chinese character for "dawn", 旦 dàn, while Táng Lán identified it as "bright", 炅 jiǒng, and so on. Helping fuel speculation of a link between Dawenkou symbols and Shang writing is their somewhat greater proximity in time (1400 years distance) and space to the Shang oracle bones, compared to earlier Neolithic finds; furthermore, the Shandong Dawenkou culture is thought by some to be ancestral to Shandong Longshan culture, which in turn may have given rise to early Shang culture. 
As with each of the other Neolithic sites, the comparison is based on only a handful of isolated pictures, and there is again no evidence of use in strings of symbols such as we would expect with true writing – none of these appear jointly.[g] Wáng Níngshēng thus concluded that they are marks of personal or clan identity rather than writing. According to Wáng, "True writing begins when it represents sounds and consists of symbols that are able to record language. The few isolated figures found on pottery still cannot substantiate this point." Keightley opines that "they probably served as emblems of ownership or identity on these pots and jades, rather than as words in a writing system". Boltz agrees that they may have been "the pre-Shang counterpart to the Shang clan-name insignia" (p. 48), but contrasts this with an actual writing system, for which there isn't any evidence at that time (p. 51–52), while Qiu concludes:
Even though the Dawenkou culture type B symbols still cannot be definitively treated as primitive writing, nevertheless they are symbols which resemble most the ancient pictographic script discovered thus far in China…They undoubtedly can be viewed as the forerunners of primitive writing.— p.39
The Chengziya site in Longshan, Shandong has produced fragments of inscribed bones presumably used to divine the future, dating to 2500–1900 BC, and symbols on pottery vessels from Dinggong are thought by some scholars to be an early form of writing. Again, this is controversial. Symbols of a similar nature have also been found on pottery shards from the Liangzhu culture of the lower Yangtze valley.
A pottery inscription of the Longshan culture discovered in Dinggong Village, Zouping County, Shandong contains eleven symbols that do not look like the direct ancestor of Chinese characters. Chinese scholar Feng Shi (馮時) argued in 1994 that this inscription can be interpreted as written by the Longshan people. Other scholars, like Ming Ru, are doubtful about attributing a Neolithic date to the inscription. The authenticity of these inscriptions is hotly disputed due to their appearance on a broken ceramic ware, an unusual feature among prehistorical text, as well as its unexpected relation to the Yi script, a modern writing system associated with an ethnic group in the southwestern China, thousands of miles and thousands of years apart from the Longshan culture in northern China.
Possible Liangzhu symbols
There are also some items, including some inscribed jades, which have symbols similar to or identical to several of the Dawenkou pictures, such as the circle and peaked crescent motif , and another described as a bird perched on a mountain-like shape; it appears that some of these may belong to the Liangzhu culture.
Between 2003 and 2006, over 240 pieces of artifacts containing ancient characters used by the 5000-year-old Liangzhu culture were unearthed within the Zhuangqiaofen ruin in Lindai town, Pinghu city, Zhejiang province. The letters were determined to be 1000 years before the Anyang Chinese script. However, the discovery did not conclude whether it was a precursor of the Anyang script. The discovered Liangzhu script were determined by academics as symbols rather than proper language.
A few geometric symbols have been found at Hūalóuzĭ (a 2nd-phase Kèshĕngzhuāng culture site) in Chang'an County near Xi'an, carved on bone and bone items which some have claimed to be ancestral to oracle bones, but this is disputed.
- Qiu 2000 p.30 divides the Neolithic graphs into two basic categories, type A (geometric symbols such as +, | and x), and type B (those resembling concrete objects, i.e., pictorial symbols).
- In fact, similar symbols which were not clearly part of any writing system, continued to be used even in the early historical periods, from the Shang through the late Zhou and Han dynasties. It has been pointed out that non-literate people are often able to use limited sets of symbols, including numerals, to convey meaning in a manner which is not writing per se; see Qiu 2000, p.30–32, and Gāo 1987, p.36.
- The traditional dating of the Shang extends earlier, to the 17th or 16th century BCE, but the oracle bone inscriptions date from the reigns of the last nine Shang kings, from Wu Ding.
- Yinxu means the Ruins of Yīn, referring to the last Shang dynasty capital at Xiǎotún, Anyang, Henan, where huge numbers of oracle bones were found, inscribed with what is still widely considered the earliest known Chinese writing.
- Banpo is radiocarbon dated to 4770 to 4290 BCE after bristlecone pine correction (Woon reports 4000 BCE), while Jiangzhai is radiocarbon dated to 4020 to 3635 BCE (Woon reports 3500 BCE): Woon 1987, p.275 & 276 respectively.
- The Banpo symbols are monosomatic entities such as x, | and +, each with only one component. See Wénwù Press 1963 p.197, plate 141 and plates 167–171.
- Each jar or potsherd bears only one symbol, except for two vessels which each have two symbols but in separate locations on the vessels; Qiu 2000, p.34; Boltz 2003 notes that "They do not occur in any form that would suggest a text, or appear to have any linguistic context" (p.51).
