Walking from Crowne Plaza Hiroshima, crossing the river is the park. There are several thick lists in the memorial hall. Outside the museum, chairs are arranged for the Pope to give speeches, and thousands of paper cranes fly. It is once again a hard-won understanding of peace. The design of the entire memorial park is very peaceful and calm. But the thought of what happened here will inevitably make people stop and think about the meaning of war and peace. May the world be peaceful forever and there is no war anymore.
