Houlong Township[1] is an urban township in western Miaoli County, Taiwan. It is bordered by the Taiwan Strait on the west and Zaoqiao Township on the east.[2] It lies at the mouth of the Houlong River. Miaoli HSR station is located in Houlong.
The township's name originates from that of a Taiwanese Plains Aborigines settlement. During the Kingdom of Tungning, the area was called Aulangsia . Other variants of Aulang existed (e.g.,). In 1920, during Japanese rule, the place was renamed, under, Shinchiku Prefecture. This name closely matched the Japanese pronunciation of the previous names but with different kanji (Chinese characters). This written form was retained after the Kuomintang takeover of Taiwan in 1945; the characters are pronounced Hòulóng in Mandarin Chinese. The Taiwanese Hokkien pronunciation remains Āu-lâng, based on the pre-1920 name.
