Knowledge breeds teenagers, educates and entertains teenagers, and criticizes XX school horizontally. Is this couplet all right?

Part I: Cultivate the fertile soil of knowledge for teenagers.

Bottom line: entertaining.

Hengpi: Happy School

This can be used as a slogan or slogan, but it is not suitable as a couplet.

Nowadays, the couplets pay the most attention to artistic conception and rhythm, and the related words that are parallel are not so particular, but the first and last words of the upper couplet and the lower couplet should pay attention to pressure. The title of the couplet is neatly written, but it is not antithetical.
