Although grass is not as fragrant as flowers and as tall and straight as trees, it has tenacious vitality. Every winter, the grass seems to disappear. Some people think it is withered, but the next spring, they will drill out of the ground, absorb the sun and rain, and grow more densely. Bai Juyi, a poet in the Tang Dynasty, wrote in his poem Farewell to Ancient Grass: "The vast grass crosses the plain and comes and goes with the four seasons; Wildfire never completely devoured them, and they grew taller in the spring breeze ",vividly describing the tenacious vitality of grass."

Every day, people come here in twos and threes, enjoying the pleasure brought by the lawn. Lawn is a paradise for children. You see, some are playing, rolling, somersaulting, some are basking in the sun, some are doing sports, and some are taking a nap with colorful tents ... It is understood that the lawn here will "receive" thousands of tourists during the day and only take a short rest at night. But when the sun rose the next day, the grass straightened up again and welcomed the tourists with a brand-new look.

"There is no fragrance of flowers, no height of trees, I am an unknown grass. Never lonely, never worried, you see my partners are all over the world. Spring breeze, spring breeze, you blow me green, sunshine, sunshine, you shine on me; Rivers and mountains, you raised me, and the earth, my mother, hugged me tightly ... "Grass sings the spirit of grass: ordinary optimism, always giving silently but always knowing how to be grateful, and never forgetting the love for spring breeze, sunshine, rivers, mountains and rivers, and mother earth.

The spirit of grass is ordinary and great, ordinary and lofty, which is worth studying.
