Send a book to an unborn child, which one can I send?

The well-known San Zi Jing is undoubtedly a good choice, especially for unborn children. Up to now, I still remember that at the beginning of his life many years ago, he was kind in nature and noble in morality. When I do something wrong, I always think of the original intention of kindness. So I recommend this one, and by the way, popularize the knowledge: Selected Stories of Saint Amethyst was produced in the Song Dynasty and revised by later generations. It has three words in each sentence, so it is called "Three-character Classic". There are about 500 sentences in the book, many of which have a profound influence on China people. The sacred amethyst was selected by UNESCO as a required reading for children's moral cultivation, and it was translated into many languages and distributed all over the world.
