Xu Xiujuan's father is a crane engineer in Zhalong Nature Reserve. Influenced by his father, Xu Xiujuan loved birds and cranes more since childhood. When she proposed to work in Xianhe Nature Reserve in Yancheng, she was strongly opposed by her parents. Father knows that it is not easy to raise cranes. How can a spoiled daughter stand it? But Xu Xiujuan's stubborn temper didn't agree, and she clamored for her father's permission to go, so his father had to comply with her.
After getting the job, Xu Xiujuan brought nothing but three crane eggs and tools for raising cranes, and took care of crane eggs in every way along the way, because the requirements of crane breeding process are very strict. If the temperature is too low or too high, little cranes will not hatch, but it is hard to beat the ingenious Xiujuan. After careful care, the little crane was finally born. Xiujuan was overjoyed and named them Dandan, Longlong and Sasha.
Life in the nature reserve is very hard. Every day, Xiujuan has to get up early to feed the small cranes. Xiujuan has to take care of the cranes and learn the breeding techniques. After she learned the breeding techniques, she took some home to raise them, but when she got off the bus, the news of Dandan's death came. Longlong also vomited blood because she missed her friends. At ordinary times, Xiujuan treated the cranes like her own children. The death of two cranes was a bolt from the blue for her. Xiujuan cried nonstop. She vowed not to be careless again. After returning to the reserve, she raised a group of cranes. Soon after, the cranes flew into the blue sky again, but unfortunately, it happened ...
A crane named Dawn was ill, so she took good care of it and it would be fine in a few days. After her illness, Dawn was very active. Xiujuan thought it was good to exercise more, so she let Dawn and Mu Ren go to the river to play. But after two days, they still didn't return. Xiujuan gave her precious life to find them ...
The sky was weeping and the ground was shaking. Everything was mourning for Xiujuan. Dawn and Mu Ren also came back. They and the cranes were crying in droves at Xiujuan's grave, as if they were sad for their lost friends ...
Xu Xiujuan, everyone remembers.
