There was an old mule(骡子). One day accidentally he fell into the farmer's well. The farmer thought for a while and said to himself that neither the well nor the old mule was important to him. So he decided to use soil to bury the old mule in the well.

    Then the farmer called his neighbours and they started to put the soil into the well together. The old mule was quite afraid in the beginning. But soon one hopeful idea came to his mind - every time when a shovel(铁铲) of soil landed on his back, he would shake it off and step up!

He said these words to himself again and again, "Shake it off and step up." This way he could fight against the panic (恐慌) and encourage himself. After some time, the mule had stepped over the well's wall. Although terribly tired, he was the winner and he saved his own life. He decided to face his difficulty bravely and not to give up, and finally he won.

    A heavy rain hit a small village. The floods (洪水) started to rise. A priest (神父) was praying (祈祷) in a church (教堂). The flood was almost above his knees. A rescuer (救助者) shipped to the priest and said, “Godfather, come up or you will die.” The priest said, “No, I'm sure God will save me. You may leave for others.”

    After a while, water covered his shoulder, the priest had to move onto an altar (祭坛). This time a policeman came over in a yacht (游艇) and said, “Come up or you will die!” The priest said, “No, I have to keep my church. I believe God will save me. You just go and save other people.” A moment later, his church was flooded. The priest had to hold firmly (牢固地) the cross on the top of the church.

    A helicopter (直升机) was flying over him where a pilot put down a rope ladder and shouted, “Godfather, come up! This is your last chance! We don't want you to die!” But he said firmly, “No, I have to keep my church. I believe God will save me. You just go and save other people. God will be with me.” Great flood soon came over. The priest was killed.

    The priest went to Heaven (天堂) where he saw the God. He asked angrily, “God, I served you honestly, but why didn't you save me?” The God said, “Didn't I? The first time I gave you a ship and you refused. The second time I gave you a yacht you refused again. The third time I sent you a helicopter you still didn't accept. So I thought you wished to stay with me in a hurry.”

    In fact, the obstacles (障碍) in our life are because we are stubborn (顽固) and ignorant(无知).

Whether you like it or not, artificial intelligence（AI）is here to stay. It bas already been used in many different fields. And now one of them is to help find the missing children. In Hubei Province, a group of 30 students at Huazhong University of Science and Technology （HUST）arc working on a special project. They have developed an AI system that restores（修复）old photos. The clearer photos allow them to better look for missing people. 

The project was set up by Sheng Jianzhong in 2020. At the time, be was a student at HUST School. One day, be came across a missing child notice. The photos on the notice were difficult to make out. "These photos may be of no practical use even if the child is around," he said. As a result, Sheng decided to use his skills to help the missing children. And to his surprise, many of his schoolmates volunteered to join him. 

Over the past three years, the team tried to develop an AI system for restoring the photos. The team has restored more than 1, 000 photos. With the help of AI system, 11 missing children were successfully found. One success story is that of Sun Haiyang. Thanks to the AI program, in December 2021, the father, Sun Haiyang found his son after 14 years of search. 

In the future, Sheng plans to build a more excellent team to run the project. The goal is not just to further improve the technology. More importantly, he hopes to see more young people work for good causes.
