The Minor West Gate is one of the fourteen gates in old Tainan city, but it was the latest one built among the eight gates in the Qing Dynasty's central city. Thus, in the 40th year of Emperor Qianlong (1775), the first generation of Minor West Gate was built under Taiwan's magistrate Jiang Yuan-Shu. It was initially called Qing Shui Men and located to the west of Tu Ji Cheng. In Emperor Qianlong's 53rd year (1788), the magistrate Yang Ting-Li presided over the city's reconstruction. A new Minor West Gate build on the side of the Tu Ji Cheng, a new Minor West Gate built. It is now known as the Minor West Gate, also known as the "Jing-Bo Gate," which means tranquil and calm. Due to its proximity to the port, the Minor West Gate has been an important commercial town since the Qing Dynasty. The Minor West Gate, the Great East Gate, and the Great South Gate were historical sites by the governor's office of Taiwan in the name of "Tainan City" In 1935. After World War II, the Tainan Municipal government planned to widen Feng-Jia road (now a section of Xi-Men road) to improve traffic, and the Minor West Gate lost its qualification as a cultural asset and had to demolish.

   The Minor West Gate of Tainan city was relocated from its original location to the Kuang-Fu campus in NCKU in 1969. When the gate moves to the position of the city wall of the small east gate section, should the city gate conform to the original westward appearance or maintain the relationship between the city and the city? Taiwanese scholar Tsai Yu-Hua claims: "at last, the Minor West Gate was reorganized by maintaining the East-West relationship in the lower section of the gate seat and maintaining the internal and external connection between the upper sections of the tower. In this way, the original westward gate seat continued to face west, but there was a problem of displacement inside and outside the city. The original west-facing tower turned to the east and outward to maintain the tower's external relationship, but the relationship with the city seat has rotated 180 degrees, becoming today's appearance. Readers may have heard the joke about the incorrect assembly of general the Minor West Gate. It is the current assembly method that should consider. Because the general public can quickly identify the city tower's internal and external relations, but not the internal and external relations of the gate seat, it is only to turn the tower outward to maintain the direction of the gate seat. Thus, the Minor West Gate's gate forehead can continue to face west and retain the forehead gate in the correct position. "
