I can't remember offhand, but it was a thick academic work based on the oracle bone script. Zhongwen.com is an English translation of the Soát-bûn-kái-chū 說文解字, which was written 1900 years before the oracle bones were dug up, so although it was written closer to the time of the oracle bones, the people of the time didn't actually have access to the characters on the bones like we do.This is interesting. Do you still remember the source? Zhongwen.com says it was pictograph of a female monkey! I never knew it either!
I'm not going to argue with this, but I'll just point out that the Red River Delta was considered part of the various Chinese Empires from the Han to the T'ang for over nine hundred years, and central government administrators were sent there for over 700 years before Chiang-chiu was founded in 686 by the general Tân Goân-kong 陳元光.If you look at the map here. Austroasiatic lies outside China proper. So Bai Yue in ancient times mostly refer to the Tai Kadai and Miau Yau group.
Hmmm.... this sort of thing doesn't really work for determining language families and who spoke what in the past. Sinhalese Sri Lankans speak an Indo-european language like English but they don't look like English people.The facial features of pure North vietnamese and pure south vietnamese are considerably different. North vietnamese usually are fair skin, oval shape eyes, which is similar to the Tai people while south vietnamese are darker skin, rounder eyes similar to the Khmer people. We should exclude migration of northerners to south vietnam and intermarriages.
