Why do children from all over the world send paper cranes to be placed beneath the sadako statue? The sadako story ​

Sadako was two years old, and two kilometres away from the atomic bomb when it was dropped on Hiroshima. Most of Sadako’s neighbors died, but Sadako wasn’t injured at all, at LEAST not in any way people could see.Up until the TIME Sadako was in the seventh grade (1955) she was a normal, happy girl. However, one day during a school RACE that she helped her team win, she felt extremely tired and dizzy. This got worse and worse, until one day Sadako became so dizzy that she fell down and was unable to get up. Her school-mates informed the teacher, and Sadako’s parents took her to the Red Cross Hospital to see what was wrong with her. Sadako found out that she had leukemia. At that time they called leukemia the “A-bomb DISEASE”. There was a low survival rate for 'A-bomb disease and Sadako was very scared.During Sadako's stay in the hospital, her BEST friend, Chizuko, came to visit her. Chizuko brought some origami (folding paper) and told Sadako of a legend. She explained that the crane, a sacred bird in Japan, lives for a hundred years, and if a sick person folds 1,000 paper cranes, then that person would soon get well. After hearing the legend, Sadako decided to fold 1,000 cranes and pray that she would get well again.Explanation:please make my answer in brain list please thank my answer please please don't delete my answer
