Many artifacts have been unearthed which add weight to this hypothesis. Comparing the Bashu inscription, which was found before the Dinggong shard but which is of slightly later date, the pottery inscriptions found at Dawenkou in Shandong, the present find at Dinggong, and other examples, the styles of the characters differ widely. But the mainstream of later development was ideographic characters.
而許多出土資料正逐漸證明這些推測，像比丁公更早發現、但年代稍晚的巴蜀文字、山東大汶口陶文及目前發現的丁公陶文等，字體形態都顯著不同，但最後發展的大勢，卻仍然是漢字。
