What is the relationship between Oracle Bone Inscriptions and modern Chinese characters?

This question first involves the question of what stage Oracle Bone Inscriptions is in the history of the development of China characters. Secondly, the relationship between Oracle Bone Inscriptions and Longshan period.

First of all, we should admit that Oracle Bone Inscriptions is a well-developed writing system, which includes primitive word-making methods such as pictograph, signifier and knowing, as well as pictophonetic characters, transliteration characters and loanwords. It can be said that the scale of writing can only be formed at a certain stage. In other words, Oracle Bone Inscriptions has moved from a purely ideographic stage to an ideographic stage. This admits that Oracle Bone Inscriptions is not a writing in the initial era of writing, but a writing that has developed to a certain stage. At the same time, due to the limitations of the written materials of Oracle bone inscriptions, as well as his engraving as an Oracle record, it is inevitable that it is not the whole picture of the Shang Dynasty figures. Just because of the long history and written materials, we can't determine the whole picture of the characters in Shang Dynasty.

Secondly, judging from the ancient Chinese characters that have been discovered, Oracle Bone Inscriptions, which was earlier than the Shang Dynasty, has not found a writing system similar to that of Oracle Bone Inscriptions. Therefore, there is no situation that these ancient Chinese characters skip Oracle Bone Inscriptions and directly affect the later Chinese characters. The only possibility is that Oracle Bone Inscriptions in Shang Dynasty was influenced by these inscriptions. The evidence is that the numbers representing the meaning of things in Oracle Bone Inscriptions are typical descriptive symbols.

So I think there is no problem that Oracle Bone Inscriptions is the direct source of modern Chinese characters, but since Oracle Bone Inscriptions is not the earliest writing, what is the direct source of Oracle Bone Inscriptions? I think the engraving in Longshan culture period should be one of its origins, but it is by no means unique. /viewthread.php？ tid= 100090
