Write a preface about autumn leaves.

It was born with a leaf. In order to bloom the beauty of life, it chose green. Bright green, let it shine. Emerald, crystal clear. Light green makes it gentle. Dark green makes it look heroic. In that season when bees are flying, butterflies are flying and flowers are blooming, it witnessed the flowers' smiles and soothed the pain of flowers' withering. It has no fragrance of flowers, but it is full of energy. Not as beautiful as flowers, but enjoying themselves. It doesn't have the charm of flowers, but it's lovely. It, for the bright spring, has given vigorous vitality. It, for the sake of spring, releases full passion. Because of it, the spring is full; Because of it, spring is graceful; Because of it, spring is moving. It, holding flowers, holding pistils, strolling among flowers.

I don't know when the autumn wind will start and spring will drift away. It's running all the way, but it's too busy for sudden changes. When it stopped to stare, it was discovered that the leaves had been colorful for many years, and it had retreated into a green suit and was immersed in autumn and yellow. "Small bridges and flowing water, old vines and old trees, faint crows, heartbroken people at the end of the world at sunset." This situation makes it feel sad. The world in my eyes is no longer bright and beautiful, and the beauty in my heart has also left in a hurry. I finally understood when I was lost: maybe things are still the same, and the only thing that won't change is my mood. Imagine that the maturity of gray is not an open-mindedness and detachment. As long as you have an ideal and know how to dive, you will eventually usher in a different future.

So, it fell in love with autumn and yellow. Although the posture is clumsy, the spirit should be elegant. In this season, it still needs to show a beautiful appearance and strive to achieve flawless quality. Even if it falls into the soil, the flower soul is still there, no regrets.
