Are there any topics in the quotations?

No, it is to express love directly through three poems. The book "Three Quotations" originated from a school of poetry initiated by the Japanese Chinese Character Association, aiming at promoting Chinese character education.

San Zi Jing originated in Japan, and many related competitions have been held in China, such as the San Zi Jing Creation Competition.

Although the "three-story book" is very popular in Japan, three-character poems were not created by Japanese, and this genre of poems was also written by poets in history. Among them, The Divine Comedy, the masterpiece of Renaissance poet Dante, widely uses the three-line poetic genre.

One hundred poems in The Divine Comedy are all written in "three lines rhyme" or "three lines serial rhyme". Each poem is a long chain composed of three lines of poems, connected by a link. On the internet, many young people in China imitate this genre and write similar advertising styles. In fact, it is not limited to three lines of melody, but sinicized and accepted by people.
