Haircut decree of Ching Dynasty and government   

Rikavong was a large tribe in 1887 when Lu Mingchuan, the commanding officer of Taiwan, was actively promoting reconciliation of indigenous people. He was aware of the influence of Rikavong and expected to reconcile Rikavong to Ching Dynasty government. On April 4, he reported to the Emperor of Ching Dynasty:

'Rikavong is the most powerful tribe and other tribes would be following its track. So Chang Chao-lien and Ouyang Chun attacked Rikavong to force reconciliation. Rikavong realized that the bloodshed was unavoidable, and after a few days of meeting, it gathered 26 tribes to reconcile to Ching Dynasty government and submitted to haircut... (Song, Long-sheng (1998) 'Aboriginal Culture in Taiwan - History of Puyuma', p. 270)  Rikavong is the dominating force over the tribes in the region, and called Puyuma Emperor. Last year, Rikavong warriors killed to people from Kasavakan and never submitted the murders. This May, Rikavong killed a few natives from Hashu Tribe natives who were carrying rice on the way back to the tribe... Rikavong has sufficient manpower and is fierce against foreign force... Rikavong claims to be the ruler of the back hill.'

    

From Ching Dynasty to Japanese colonization, Rikavong was referred to as 'Rikabong', 'Rikahong', 'Chun-hua', 'Di-hua', 'Lika' on literatures and documents. The early documentation of Rikavong was found during Dutch colonization, when Rikavong was called 'nikabon'. Rikavong was portrayed as a large tribe frequently engaging in conflicts in official documents.
