During the Qing Dynasty, the Russians built a prison in Dalian. Now it has become a free tourist attraction Dalian Lushun. It has an important strategic position. It has become a springboard for the powers to invade China more than a hundred years ago. The centuries-old ancient architecture also became the evidence of the invasion of China by the powers. The former site of the Japanese-Russian prison in Lushun has now become a free and open tourist attraction. The prison was built in 1902 at the end of the Qing Dynasty. It was built by the Russians and later expanded by the Japanese in 1907 to form today's scale. In the Japanese-Russian prison, the blue bricks were built by the Russians, with a total of 85 cells, and the red bricks were later expanded by the Japanese, with a total of 253 cells. The cell area is small and several people are crowded into a cell. The conditions are very difficult. There are not only Chinese in this prison, but also some Japanese and Koreans. The most well-known "prisoner" held here is the Korean emperor. An Zhonggen assassinated Ito Bowen at Harbin Railway Station in 1909, and was then detained here. He was righteous in prison the following year. The Japanese-Russian prison has a history of more than 100 years. It is impossible to count how many patriots are being held in custody. Because the Japanese evacuated, all the documents were burned in order to cover up their crimes. This is a unique prison in the world. It is a prison built continuously and continuously by two imperialist countries in a third country. It has become a human hell for imprisoning, persecuting and slaughtering the Chinese people and international progressives. Chinese prisoners are subjected to the most severe persecution here. Prison regulations, Japanese prisoners can eat white rice in prison, Korean prisoners can eat millet, and Chinese prisoners can only eat moldy sorghum rice in prison. In the prison, the scene of the Japanese invaders killing the prisoners was reproduced. There was also a gallows room, and on the hill next to the prison, there were still countless skeletons of executed prisoners.
