Set slogans for classrooms, gardens, and restaurants, and use poems, famous quotes, and aphorisms.

Classroom

The edge of a sword comes from sharpening, and the fragrance of plum blossoms comes from the bitter cold.

Everyone is responsible for the rise and fall of the world. (Gu Yanwu)

Learning without thinking leads to waste; thinking without learning leads to peril. (Confucius)

Work is accomplished by hard work, waste by play, success is achieved by thinking, and ruined by following. (Han Yu)

Where there is a will, there is a way. (Book of the Later Han Dynasty)

Garden

The leaves are endlessly green, and the lotus flowers are red in the sun.

After collecting hundreds of flowers into honey, it will be sweet to whomever you work hard for.--Tang Luo Yin

Flowers growing on dunghills are often more beautiful than flowers planted in gardens.--UK

Restaurant

Who knows that every grain of food on the plate is hard work.

Every grain of porridge should be thought of as hard-earned; half a thread and half a thread, always thinking about material resources. Difficult.

What falls down is the leftover food, and the blood and sweat is lost.
