How is Braille "Braille"
1829, louis braille, a French blind man, created a writing method for the blind-Braille. This kind of creation has brought great happiness to the blind, but his life of fighting for the interests of the blind is little known. Braille was born in a poor harness manufacturer's home in France. When he was three years old, he accidentally dropped his hand while playing in his father's studio, stabbing one eye, and soon the other eye became infected, leading to blindness. Braille's parents didn't give up training the blind child. Father used nails to form letters on the blackboard and taught him to read carefully. Later, he went to the primary school in the village to study. Braille studied hard and was smart, and was deeply loved by teachers and principals. At that time, in the school for the blind, the textbooks of blind students were printed with enlarged lead-printed ordinary letters, which were glued to the table like sewing machines when used. When children are reading, it takes a long time to understand a sentence by touching it with their fingers one by one. Moreover, the number of teaching materials is very small, and most courses are dictation. Braille studied hard, got good grades and was eager for knowledge, but there were no more books to read. From this, he realized that it was necessary to create a kind of Braille that was easy to read and write, thus opening the door to the treasure house of knowledge.

Once, he happened to hear that a French officer had invented a "night code" that could accurately transmit information at night. Braille immediately ran to consult. It turns out that in the battlefield, in order to prevent the target from being exposed, you can't just light up at night. The officer figured out a way to drill a small hole in the thick paper with a drill bit to make the back of the paper protrude slightly. By touching the back of the paper with their hands, they can distinguish the code words of "small holes", and they use these perforated thick papers to transmit information to each other. Braille was inspired by it. Since then, Braille has devoted himself to studying this kind of Braille. He was once again inspired by people's images. He thinks that everyone has two shoulders, two arms and two knees. If you add a bump to each of these parts, wouldn't it be six enlarged bumps? What an interesting six o'clock! After some painstaking arrangement, a set of French alphabet schemes with different arrangements and rules have been drawn up. There are sixty-four variants, six bumps and one blank.

1829, Braille added mathematical symbols and music notation to the original scheme. For the first time, he showed the plan to all the teachers and students of the Royal School for the Blind and asked the school leaders to review and promote it. Braille has been teaching since she graduated from the school for the blind. Despite his busy work, poor health and great setbacks, he was not discouraged. Because of its great advantages, his Braille is easy to touch and write, which is very popular with students. It was officially finalized in 183 1. The following year, the world's first book in Braille was published, which laid the foundation for publishing higher-level natural science books in Braille.

1887 "Braille with Braille" is internationally recognized as 7a68696416fe59e7ad943133431336639. Braille brings light to countless blind people.
