Atayal people
The Daxi area was occupied for several thousand years by the Atayal people. The Atayal called the local river (modern-day Dahan Creek) "Takoham" in their native Austronesian language. This gave rise to similar names such as "Toa-kho-ham" (; also ) in Hokkien and "Taikokan" in Japanese via transliteration.
