Personal life

Little girl invents more, a celebrity in Juvenile Science and technology circle

In August 2002, the mobile phone for the blind designed by 7-year-old Li Nanjin took part in the "Haier science and Technology Award for Chinese children", which is known as China's "youth Nobel Prize". In November, the "mobile phone for the blind" design was selected in the top 30 in the preliminary evaluation of more than 60000 entries nationwide, and Li Nanjin was the smallest. On December 17, when Li Nanjin went to Beijing for his defense, he was the "champion" of 30 middle and high schools and was one of the 10 first prize winners of the "Innovation Award". The "mobile phone for the blind" designed by Li Nanjin has five functions: using the Braille number key which is convenient to touch, using the touch graphic function key, adding the voice prompt system for incoming calls, adding the radio function, and selecting the efficient and safe battery to replace the power supply. Experts from Haier Group believe that Li Nanjin's design can be completed by using the existing technical level. At that time, the evening news reported Li Nanjin's award-winning situation and her small inventions, which attracted readers' attention. She was also rated as one of the top ten news figures of that year. after that, Li Nanjin invented the telephone for the blind, shoes for the blind and wind-driven mosquito repellent, which also won her many awards. Li Nanjin is already a celebrity in the youth science and technology circle.

Invention comes from life. Her family lives next to the school for the blind

after reading Li Nanjin's inventions, many people will find that many of them are related to blind people. Why? It turns out that Li Nanjin's home is next to the Qingdao school for the blind. Li Nanjin often helps the students in the school for the blind. On weekdays, she recycles hard paper shells and calendar paper, and then sends them to the school for the blind to write Braille. After getting along with the students in the school for the blind for a long time, she noticed many inconveniences in the life of the blind and hoped to help them solve the difficulties. in a newspaper selection topic of the science and technology activity group, Li Nanjin proposed to design a mobile phone for the blind, so that those who can't see the keys can use the mobile phone freely. After searching for information and absorbing advanced foreign experience, Li Nanjin's "mobile phone" was successfully manufactured. in addition to the mobile phone for the blind, Li Nanjin's other inventions are also inspired by life. She felt that it was inconvenient for the blind to walk, so she invented blind shoes. A "antenna" was installed in the front of the shoes. When walking, if the front end of the antenna touched an obstacle, the blind could know. Seeing that when opening and closing the door, there are always flies taking advantage of the opportunity, Li Nanjin wrote a paper to expound the theory of wind driven mosquito repellent.

Invention depends on interest, mother almost buried her

Ms. Cao, Li Nanjin's mother, said that she almost buried her child's creative talent at the beginning. Ms. Cao said that when the children said they wanted to use mobile phones for the blind, she and the teachers in the school for the blind didn't agree. "In fact, most of the blind people can use ordinary mobile phones normally, so why make them? Besides, this invention has no scientific and technological content. We don't think it's an invention! " However, Fu Long, a science and technology teacher, is very supportive of Li Nanjin. The final result is that Li Nanjin won the Haier science and Technology Award for his "no technology content" invention. Li Nanjin's good friends in the school for the blind also spoke highly of her invention. At this time, Ms. Cao understood that for children, the real significance of scientific and technological inventions lies in the innovation of thinking. As adults, we should not examine childlike innocence from our own perspective, let alone stifle children's creativity and imagination. However, for the moment, scientific and technological inventions do not involve parents' nerves like artistic expertise and Olympic Games, because making small inventions does not seem to directly help the future "development" of primary school students. In this regard, Ms. Cao believes that small inventions are children's interests, and can not be viewed from a utilitarian perspective. Ms. Cao admits that scientific and technological activities do involve children's energy. However, since she fell in love with small inventions, she found that children love reading, and the popular science books at home have become children's good partners; children are good at observation, and more and more know how to care for others, and when they encounter difficulties in life, she always hopes to help solve them; children love thinking, and their thinking is active, which is also very helpful for daily learning. "It can be said that making small inventions has nurtured children from all aspects of morality, intelligence and physique."

True love, infinite invention

Li Nanjin, a 9-year-old young pioneer of Qingdao experimental primary school, Shandong Province. In her daily study and life, she always strictly demands herself according to the standards of young pioneers, actively participates in various activities of young pioneers, and strives to be an excellent representative of Contemporary Young Pioneers by starting from herself and the little things around her.

Love learning

Li Nanjin had a strong desire for knowledge since she was a child. The first two weeks of kindergarten, she proposed to go to a real school. After being approved, she became the youngest good student in the class with good grades, and the total score of each semester was excellent. She loves reading books, likes reading all kinds of extracurricular books, and is never tired of reading encyclopedia books. She once won the title of "little bookworm who loves reading".

find in helping others

Li Nanjin is willing to help others and has won the titles of "little pacesetter of code of conduct" and "three good students" for many times. a local media once proposed that we should give the discarded calendar paper to the blind school students for homework. After Li Nanjin saw the proposal, all the paper waste products in her home should be examined by her. When she went shopping in the store, the commercial publicity materials discarded by customers were also collected by her, and the scratch resistant hard paper that met the requirements was regularly given to the blind school students. She actively participated in various activities organized by the school In the fight against SARS in 2003, Li Nanjin proposed to his parents to donate 2000 yuan of prize money to the "angels in white" who were fighting in the front line. she is not only a "little messenger of love" in her class, but also a "little volunteer" in her mother's work unit (Qingdao children's Hospital, Qingdao children's heart center). Li Nanjin often uses Saturday afternoon time to go to his mother's department to draw pictures and tell stories for sick children, and has also established a deep friendship with some of the children patients.

Love nature

Li Nanjin loves nature and has a strong sense of environmental protection. When making the model of mobile phone for the blind, all the materials she used were waste materials she had accumulated. She is kind-hearted and loves animals. She learns about animal protection from animal world and man and nature. She delivers water and food to wild kittens, bandages injured puppies, lets caged birds fly freely, and mumbles with captive animals. In October 2002, she won the excellent award of painting in the first "little citizen" moral construction practice and innovation activities.

Love to invent

Diligent use of the brain, good thinking and love of invention are the most prominent characteristics of Li Nanjin. She usually likes to observe things, like to ask "why", often ask teachers and parents some strange questions. Her family lives next to the Qingdao school for the blind. She usually observes that it's very inconvenient for the blind to go out. She can only use the ordinary telephone of the school for the blind to contact her family. So she has the idea of helping the blind. She decides to design a mobile phone that can be used by the blind, so that the blind can also enjoy the convenience and fun brought by this modern communication tool. At the beginning, her idea was not recognized by everyone. Even a teacher in the school for the blind thought that she was superfluous and had no practical value. Li Nanjin was not discouraged. With the support and help of counselors, teachers, students from blind schools and parents, he overcame many difficulties. Because there are too many Braille number points to express on the mobile phone, careful Li Nanjin found that the first part of 0-9 digital braille is the same, so he removed them and changed them into simple Braille, making the Braille on the mobile phone of the blind become a practical and operable digital Braille. After many modifications, Li Nanjin finally successfully designed and manufactured a mobile phone model for the blind. In December 2002, as the youngest player in the finals, 7-year-old Li Nanjin went to Beijing to participate in the 2002 (first) China children's Haier science and technology competition finals jointly sponsored by the National Youth Working Committee, the Chinese Academy of juvenile Sciences and Haier Group Company, and finally won the "Innovation Award" (first prize) with the advantage of "a wonderful combination of pure love and scientific and technological value".

Won awards

After winning the prize, Li Nanjin paid more attention to the blind school students, and successively invented and designed a series of works such as the blind telephone, the blind microwave oven, the blind football and the blind shoes. In April 2004, the "blind telephone" won the second prize of the invention and Innovation Award in the second "information technology innovation and practice activities for primary and secondary school students" in Shandong Province and China. Li Nanjin is most afraid of mosquito bites in summer, but her grandmother's family lives in a bungalow, where there are many mosquitoes. Every time before she enters the room, she will try her best to fan them away with a fan, which is very hard. Li Nanjin, who loves to use his brain, imagines whether there is something that can automatically wind and form a wind wall, so that he can easily stop mosquitoes? So another fantastic idea was born
