The Gangkou Hamlet is located about 500 meters from the north bank of the Xiuguluan River in Fengbin Township, Hualien County. The traditional name is Makotaay, which means the muddy stream because there is a small stream on the north side of the hamlet and when it rains the stream becomes muddy. In the past, the ancestors of the Gangkou Hamlet lived in the old Ciporan Hamlet. After the Cepo’ Incident in 1887, the tribesmen who had moved to other places were called to return to settle in a hamlet not far from the original site, which is the present Gangkou Hamlet.
