antithetical couplet
A piece of chalk is clean, a three-foot platform is sunny and rainy all the year round, plus five internal organs, six lungs and seven mouths, and Jiu Si's ten creams, teaching will be done well, and sweat will be sincere and fragrant.
Ten volumes of poems, nine chapters, eight articles and seven latitudes of geography, plus six arts, five classics, four books, three characters and two elegance, are tireless in teaching people and diligently cultivating talents, making China prosperous.
praise
A piece of chalk does not rot, and a three-foot platform cultivates all the year round. I've been busy for six or seven days, thinking for a long time, and teaching you a thousand words in every way. Happy holidays to the teacher! !
