Photo taken on April 2, 2019 shows a view of the Pohyon Temple in Mount Myohyang, the Democratic People's Republic of Korea (DPRK). Nearly 70 years ago, in October 1950, hundreds of thousands of Chinese young men and women in uniform crossed the northeastern border to the Democratic People's Republic of Korea (DPRK), fighting in the Korean War alongside with their Korean comrades. Nowadays, hundreds of Chinese people cross the Yalu River from northeast China's city of Dandong -- by train or by bus -- to the DPRK to sightsee. Others seek to uncover wartime stories.
