Anyway, like I said, I was revisiting that post and checking on comments made about it and I found this link that someone has shared in response to someone else's post about my post hehehe..
So I am sharing it here. It says some scientists are conducting research and suggested that the Malays in Peninsula Malaysia are in fact, Dusuns who migrated there. And Yunnan China is again mentioned. Click on 1Malaysia for the link.
