 
          Building a fish lake was not an easy task. Whenever David wanted to give up, the picture of
        
        
          those lively roses appeared in front of him. After overcoming all the obstacles encountered in
        
        
          creating his fish kingdom, David became a rich man in the Gobi Desert. In his fish lake, there
        
        
          were a variety of fish. As the water is especially fresh and clean in the desert, the fish he bred
        
        
          were tastier than any fish bred in other areas. As a result, the selling prices of his fish were 30
        
        
          percent higher than any other fish. Many merchants bought fish from his lake and sold outside
        
        
          the desert to make profit.
        
        
          David was a billionaire now and his dream of returning home came true. David was a
        
        
          generous man. With such a big wealth, he donated a lot to charity and also gave some fish to his
        
        
          poor neighbors in the Gobi Desert. In fact, he enjoyed his life in the desert very much.
        
        
          Did you wonder why David can become a billionaire so easily? There was a secret behind.
        
        
          When David was drinking water from the lake one day, a charming fairy which was holding a
        
        
          wand appeared in front of him. The fairy said to David friendly, ‘This is the lake of luck. You are
        
        
          the first person who discovers the lake. According to our tradition, we will bless you and make
        
        
          your dream come true.’ David was shocked. Before he could give any response, the fairy left.
        
        
          In a flash, many years had passed. David was already 104 years old. After his 104th birthday,
        
        
          he died in his beloved desert with his family by his side. Before he stopped his breath, he said
        
        
          thank you to those encouraging roses as well as the helpful fairy. According to a rumour, David
        
        
          became the brightest star in the Gobi Desert after he died. He led every person who was lost in the
        
        
          desert to the lake to help them survive. If you go to the Gobi Desert, remember to look at the sky
        
        
          at night. The sky was huge and without the light pollution, you must have the chance to see the
        
        
          sparkling star guiding you to the lake.
