How to write the placard of campus flower bed?

The sign on the edge of the flower bed-"The flowers are smiling, please walk around!" "Flowers are angels, please protect them!" "The flowers are blooming, please don't pick them!" The slogan on the lawn-"The grass is growing, please cherish it". "Don't trample on the lawn. ""The grass is reluctant, and everyone cherishes it. " "It's a pity to step on the green grass." Even Ping Li, a student who has a headache in writing a composition, wrote: "Leave flowers and plants to add color to life." Such a poetic sentence. "The grass is sleeping, please don't disturb it." "The grass is green, how can you stand it?" The sign by the pool-"The water is unpredictable, please don't swim." "Protecting water resources is everyone's responsibility." "Water is the source of life, please cherish every drop of water." Please don't destroy the fish's home. The sign next to the light switch-"I take care of me in the dark and you take care of me at dawn." "Come and go in a hurry, don't forget to turn off the lights." Please save every kilowatt hour! "Please don't make me blink!"
