Located within Chung Cheng Park, the National Military Veterans Affairs Park is the first park in Taiwan to combine decommissioned weapons and equipment from the Army, Navy, and Air Force. In addition to seeing century-old cannons bearing the scars of countless battles, visitors can also see many modern weapons of war. Visitors can also touch these weapons and equipment that they would not normally see, making for a truly novel and interesting experience.
The various retired weapons of the Republic of China Army displayed in the Military Service Park, though retired from service, still look impressive and bear witness to the history of the Army's defense of the nation. These include: F-104G Star fighter jets, Victory Goddess missiles, naval 5-inch guns, amphibious assault vehicles used by the Marine Corps, and old cannons that once served at the Baimiweng Fort, among many other heavy weapons. Even the mainmast, anchor, and propeller of the former Guiyang warship are on display, creating a truly awe-inspiring sight. The Victory Goddess missiles in the park were high-altitude interceptor missiles imported from the United States in 1959 and served as the mainstay of the Army's missile forces until they were replaced in 1997 by the Tien Kung missile, which was developed domestically by the Republic of China Army.
The most historically valuable exhibit in the Yizheng Park is an Armstrong breech-loading steel cannon, preserved since the Qing Dynasty era under Governor Liu Mingchuan. It has an 8-inch muzzle caliber, an effective range of 5 kilometers, a length of 5.55 meters, weighs 12 tons, and features a left-hand rotating breech and a helical locking breechblock. It is one of the very few large, authentic cannons remaining from the Qing Dynasty era in Taiwan, and the only authentic cannon still existing in the Keelung fortification area. Originally located at the Baimiweng Fort in Keelung, it was moved to the National Defense University after World War II, and then returned to the Keelung City Government in 1994, where it is now located in Meiyuan, the Yizheng Park, where it remains to this day.
The Eunuch Park has signs prohibiting climbing on decommissioned weapons. These signs are placed in warning areas to prevent accidents and protect the weapons on display. Visitors are asked not to climb on the weapons to avoid damage and to ensure their own safety.
