Sanyanshu originated from a poetry genre initiated by the Japanese Chinese Character Association to promote Chinese character education. It often takes something as the theme and requires the author to express it in the form of poems with less than 60 words and three sentences. It can be said that the three-story book is a kind of three-line poem.
