Lungching Township sits near the border of Taichung City and Taichung County, stretching out toward Taichung Harbor along Chungkang Road, and out toward the foot of the Tatu Mountains. If you look out from Tunghai University in Taichung, you can see a stand of royal poinciana trees-and it is there you'll find Lungching.
