What introductory books for writing poetry are worth recommending?

The book "The Enlightenment of Rhythm" is good. It trained children in ancient times. Rhyme, including astronomy, geography, flowers and trees, birds and animals, people, utensils and so on. From the singles and doubles to the twins, and then to the three sub-teams, the sound and rhyme are coordinated and catchy, from which they get training in pronunciation, vocabulary and rhetoric.
