Mr. Parveen Aziz comes from Malaysia, he is one of the friendliest people I have ever met. In 2017, he took part in the Canton Fair and found our booth. "Wow, this is a new thing in our country, can such a book make a sound? "he said. Then he told us his idea on a new design, his request is that this not only with sound sensor but must also have wind sensor, and our designer spent around a week working out the design of the entire book, after sample confirmation, we started the mass production of 5000 pieces. We all believe that sound books will replace ordinary paper books and become a new type of educational toy for children.
