Extending from the exhibition of the Memorial Hall, it led the visitors to walk around the city and to feel the historical pulses of it. In June, the representatives of the students studying in China and the volunteers of the Memorial Hall took part in the "Ning Zai – City of Peace Memory Design Exhibition". They revisited the Nanjing safety Zone, a refugee station conducted by our international friends during the Nanjing Massacre and visited the Fort Group on the Purple Mountain in Nanjing, experiencing the pulse of nature and history and resonating with the city.
