Four lines. Bozhou is a fourth-tier city. Bozhou City is a prefecture-level city under the jurisdiction of Anhui Province. Although it was previously listed as a fifth-tier city, in recent years, with the continuous improvement of economic development and urban construction, it has successfully ranked among the fourth-tier cities and among the four major cities. It should be noted that there is no official unified standard for the line-level division of cities, but the result is based on the comprehensive evaluation of many factors, so the division of different institutions or individuals may be different. But on the whole, Bozhou's economic development and urban construction level are constantly improving, and there is still great potential for development in the future.
