On this day, Shanghai South Railway Station was crowded with people carrying baskets and bags, strong people holding old people and children, and people anxiously waiting for the train to arrive at the station quickly and take them away from the war.

Suddenly, the alarm sounded harsh, and the harsh voice hovered over the station. Then, people heard the huge roar of the plane: ah! Not good! Japanese planes are flying in the direction of the railway station!

"The devil's plane is coming, hide quickly!"

"Quick, quick, hide!"

People ran in panic, but no one knew where to hide. The whistle of the bomb was accompanied by an earth-shattering explosion. The panicked people fled like frightened birds.

One shell after another rained down, and people's screams, shouts and groans were mixed with the roar and explosion of shells. The noisy railway station in the past has now become a hell on earth.

A couple clasped their son's hand. They are running around and there is nowhere to hide. With a deafening explosion, the child's mother fell. She let go of the child's hand and shouted in her last voice, "Take care of the child."

The father abandoned all his possessions, picked up the child and ran desperately in the smoke to find a safe hiding place for the child.

Finally, they ran to the platform next to the railway, and he stuffed the children into the gap under the platform. There was a loud noise, the platform collapsed and the child's father disappeared.

I don't know how long it took, but the explosion stopped, and occasionally there was the sound of buildings collapsing. The children under the moon crawled out of the gap. He cried and shouted "Dad-Mom-"How helpless and painful his crying was. There was no answer around, and there was silence, and the world seemed to stop breathing. He tripped over piles of collapsed objects and climbed to the edge of the railway. No father, no mother, no one around. His hands, body and face were covered with blood, as if he had fallen in a slaughterhouse.

I don't know which is the blood of the wound and which is the blood of the deceased. He doesn't understand why the world has become like this, why someone wants to drive them out of the house, why his parents just disappeared, why, why?

The story behind the photo

"Boom-boom-"Japanese planes dropped one bomb after another. As soon as the air defense alarm was extended, it rang "meowed". Suddenly, the house collapsed, the tall steel frame was blown to pieces, the ground was a mess, bricks, mud blocks and wood blocks were everywhere ... Hundreds of people in the station were shocked at once, and everyone's face showed a look of horror. Some people were killed by the bombs before they could react. Cries, cries for help, footsteps, more and more people fell, there were bloody people everywhere, as well as lost luggage and shoes. ...

This is the scene of Shanghai South Railway Station on August 28th, 1937.

Shanwazi didn't know when he was pushed to the railing. He is covered in blood and feels very painful, but he doesn't know where it hurts. He wiped his eyes to see his parents. Their family was going to stay at Grandpa's house in Wuxi countryside for a few days by train today, but I didn't expect it. ...

After a long time, it was quiet around, leaving him alone. He sat down, tears streaming down his face, crying his heart out. ...

With the passage of time, people came out of the grief after the bombing, and the refugees gradually merged into a stream of people, all wanting to stay away from this war and this disaster. ...

At this moment, a kind-hearted man came and found the helpless orphan. He took Shanwazi and walked to the rear together. Shanwazi started a new life, and he will never forget this day.
