I especially like the introduction to common Braille writing tools in the book, and the sections on mathematics and English Braille are also very interesting. Moreover, this book also keeps pace with the times and incorporates new results and new technologies. It feels like it really keeps up with the times. In short, I think this is a valuable book and recommend it to everyone!

The content is very substantial and full of knowledge. It's not easy to learn. . .

Super good, very suitable for beginners

Who is this for? For parents and teachers?
