People often said Thomas Edison was the greatest genius(天才) of his age. There are only a few men in all of history, who have changed the lives of other men as much as the inventor of the first useful electric light. But Edison could never be pleased only because someone said he was a genius. “There is no such a thing as genius,” Edison said. He thought what people called genius was mostly hard work.

     But Edison was a thinker as well as a worker. From his earliest days as a child he wondered about the secrets of nature. He tried to understand them, and then he tried to learn what he could usefully do with them.

     Edison enjoyed thinking. He knew that most people would do almost anything instead of the difficult work of thinking, especially if they do not think very often. But he knew, too, that thinking could give men enjoyment and pleasure.

     Edison could not understand why anyone could not be interested in life. As he loved to think, he also loved to work. On the day he became 75 years old, someone asked him what idea he had about life. “Work,” he answered, “Discovering the secrets of nature and using them to make men happier.” He said he had enough inventions in his mind to give him another 100 years of work.

    Huang Qingyun spends her life telling stories to children. Now though she is in her nineties, she has no plans to stop.

    "I did this for children, from the first day I started to write stories. I am old now, but I still want to go on telling stories to children," Huang said.

    Born in Guangzhou in 1920. Huang spent her childhood in Hong Kong and her favourite hobby was making up stories for her elder sister.

    In 1935, Huang went to university and studied Chinese. During this period, she was greatly influenced by the well-known Chinese educator Tao Xingzhi and decided to become a primary school teacher. However, instead of being a teacher. Huang found another way to educate children. During World War Ⅱ, Huang often told stories to homeless children at the Little Children Society, a charity (慈善机构) set up by a professor from the University of Hong Kong.

    Huang also started a column (专栏) called "Sister Yun's Mail Box" in Xin Er Tong, a children's magazine set up in Hong Kong in 1941. From then, Huang officially started writing and created a large number of stories for children. Huang spent about 30 years at the magazine working as chief editor (主编) in Guangzhou.

    Huang retired in 1987. She moved to Hong Kong and went on creating stories for children, including I Love Hong Kong, Children from Hong Kong and Shoes Brothers.

    "What l wrote were all for children, and for me, writing fairy tales is my favourite," Huang said.

    There were two fishermen named Tom and Jack. They were close pals. One day they went out to catch fish together and have a fish meal in the field. They sat at a distance and started hunting for fish. Tom got a big and beautiful fish in a few minutes. He was so happy and placed the fish in the ice box. He decided to cook the fish in the noon. He spent some more time and caught a few more fish. He decided to make a grand meal with the fish. Also, he froze a few fish to take them back home.

    After an hour or so, Tom went to Jack to see if he needed any help. Jack said no. In a few minutes, Jack caught a large fish. However, he put it back into the lake. Tom was surprised at his act, but he remained silent. Jack caught more big fish, and put them all back into the lake. Very frustrated, Tom angrily asked him, "Are you mad? Why do you put your fish back into the water? They are beautiful and big!" Jack replied, I know they are big, but I don't have the big pan(锅) to cook the big fish! So I'm looking for a smaller fish that fits my cooking pan! God is troubling me today."
