 These incoming migrants almost certainly spoke languages related to Austronesian or pre-Austronesian, although their phonology and grammar would have been quite diverse.Blench considers the Austronesians in Taiwan to have been a melting pot of immigrants from various parts of the coast of eastern China that had been migrating to Taiwan by 4,000 BP These immigrants included people from the foxtail millet-cultivating Longshan culture of Shandong (with Longshan-type cultures found in southern Taiwan), the fishing-based Dapenkeng culture of coastal Fujian, and the Yuanshan culture of northernmost Taiwan which Blench suggests may have originated from the coast of Guangdong.Based on geography and cultural vocabulary, Blench believes that the Yuanshan people may have spoken Northeast Formosan languages.
