Hiroshima is a city rebuilt by Japan after World War II. Since the United States threw an atomic bomb at Hiroshima after World War II, the city was almost in ruins. In order to commemorate the disaster caused by the atomic bomb explosion in Japan and maintain world peace, the Japanese government set up a memorial park and memorial hall at the original explosion site of Hiroshima. I hope that the world will remember the suffering brought by war and cherish the peaceful world!
