The two cities, also known as the two imperial palaces, are located in Kyoto, Japan. They are the headquarters of the shogunate general in Kyoto. The two cities, built in 1603, are the symbol of power of the Edo shogunate. There are about 500 meters in East and west, 400 meters in North and south, and trenches. Two corridors called "oriole floor" in the city will make oriole-like sounds when people walk on them. They are the police organs set up by the shogunate rulers to protect their own safety. The Royal Palace of Benwan and the Royal Palace of Erzhi pills are the main buildings of the two cities. The architecture of "Erzhi Wan" is very distinctive. The walls and doors inside the hall are painted with famous paintings by Safari painters, which are exquisite. The blooming season of plum and chrysanthemum is a good time to visit. Ertiaocheng is the garrison of General Tokugawa in the Edo era when he was making pilgrimage to the Emperor, which is equivalent to the palace. Historically, only the early general Tokugawa Jiakang, the second general Tokugawa Xiuzhong and the third general Tokugawa Jiaguang and the last general Tokugawa Qingxi lived here. Historically, the famous "Dazheng Fenghuan" took place here, where the headquarters of Tokugawa Celebration took place during the battle of Bird Voice. The two cities have witnessed many important historical events. Although they are not as famous as Jilu City, friends who like history must not miss them here.
