The first part of Three Sinogram Verses Using Free Radical presents 56 verses, which collects the most frequently-used radicals that are characters by themselves, like “人”，”日”,”月”. Each verse is composed of three characters, two single characters and a combined character thereby formed. The two single characters are respectively two radicals; therefore, one hundred and twelve radicals are introduced in this primer. Every four verses form a stanza, metrically precise and beautiful so as to greatly facilitate recital and memorization.
