Taipei Basin (台北盆地) is a geographic region in northern Taiwan. It is the second largest basin in Taiwan. The basin is bounded by Yangmingshan to the north, Linkoumesa to the west, and the Ridge of Syue Mountains (雪山山脈) to the southeast. The shape of the basin is close to a triangle. The three vertices are Nangang, Hueilong of Sinjhuang, and Guandu of Beitou.
The main rivers in Taipei Basin include Danshuei River, Keelung River, Dahan River, and Sindian River.
Taipei City is the provisional capital of the Republic of China (ROC) and the largest city on Taiwan island.
Taipei City is located in the TaipeiBasin in northern Taiwan and is bordered on the south by the Sindian River (Hsintien), and the Danshuei (Tamsui) on the west.
Both Hanyu Pinyin, which is used both in the PRC and in Taipei City itself, and Tongyong Pinyin, which is mandated by the central government, reflect this pronunciation, romanizing Taipei as Taibei, a spelling that is closer to the Mandarin pronunciation.
