Division into five regions
The scheme of division into five regions is a fusion of the tetrachotomy and hexachotomy scheme. Although no specific names are given in each division, it is the most commonly used scheme among the highest divisions of the central government. This scheme is used by the Joint Service Centers under Executive Yuan and the jurisdiction of High Court Branches under Judicial Yuan.| No. | Present divisions | Joint Service Center | High Court Branch |
