The old name in Chinese (Chinese: 水返腳; pinyin: Shǔifǎnjiǎo; Pe̍h-ōe-jī: Chúi-tńg-kha; literally: "water returning foot") refers to the fact that the tide from the Keelung River stops at Xizhi and goes back to the sea. During the Japanese rule, the place name was changed to 汐止 (shiodome(しおどめ?), literally "end of tides") and was under Shichisei District (七星郡), Taihoku Prefecture. This is the source of the current name.
Xizhi is located in the Keelung River valley between Taipei and Keelung, which is an important transportation corridor. The old Jukando Highway and Jukan Railway Line (縱貫線) passed through here during the Japanese occupation. Currently both north-south freeways (National Highway 1 and National Highway 3) as well as the Western Line railroad pass through Xizhi.
A Taipei Metro (Taipei Rapid Transit System) station is planned for Xizhi.
