The contact between Tamalakao and Rikavong 

Tamalakao is now called Taian Tribe. The famous singer Chang Hui-mei was from Tamalakao. It was located on the mountain to the north of Rikavong. Tamalakao had close relationship with Rikavong as told by Priest Ceng Chian-chi (1993: 142-143): 

" A group of Toko natives came down the mountain from Tusariyariyang, they included the ancestors of Taian and Chulu Tribes. They traveled over the mountain and toward north, and reached Kindopor, a mountainous region over Tona inhabitation. The ancestors of Taian Tribe wanted to stay and joined the ancestors of Tona, yet for some unknown reason, they left the region. So Tona natives called Puyuma 'talibeka', meaning 'the tribe went down hill'. After traveling down the mountain, the ancestors of Taian Tribe met some people speaking the same language; they were Rikavong natives. Rikavong was not located in the area today, but at the cemery south to the Tona. Due to same language and background, ancestors of Taian Tribe expressed their willingness to join Rikavong natives. However, Rikavong natives refused the request for the reason of insufficient space and dense population. The ancestors of Taian Tribe were force to the north, and attacked by Rikavong natives continuously. Rikavong natives even burned beehives, so bees could attack Taian natives. At last, ancestors of Taian Tribe were forced to move to north and settle in Taian."
