泰雅族
Legend has it that the Kavalan arrived by sea from the east and that when they saw the stunning beauty of this location, they decided then and there to settle this bountiful land. The newly arrived Kavalan fought many battles against the local Atayal people, and in the end the Kavalan drove the Atayal into the mountains — true to their name "Kavalan", which means "flatland people". That name subsequently morphed into "Hamalan", ultimately yielding the modern-day "Yilan City". They were referred as 36 Kavalan tribes (蛤仔難三十六社), although there were more than 60 tribes. In the past, tribes north of the Lanyang River were called Sai-sè-hoan (西勢番) while those south of the river were Tang-sè-hoan (東勢番).
