Laughter is a common thing. Annie Baby once said, "I smile. Whenever I am sad or happy, I only smile. " Indeed, many people always bury all their misfortunes with smiles. So, "there are always so many happy people", I forget who said that. I followed passers-by carefully, collecting smiles on their faces and putting them in bags, whether good or bad.

I set foot on my road, looking for and collecting smiles.

Passing by the wedding dress shop, you will see exquisite wedding photos, which freeze the most beautiful outline in the world and outline a smile called "happiness". I put it in the bag and put it in the softest position.

I walked on and passed a house with an open door. I clearly saw a child squatting in the corner and laughing. I went over and asked, "Little brother, what are you laughing at?" He looked up at me, his eyes cold and desperate, and he continued to smile, his eyes foggy. I saw his parents' divorce agreement on the table ... I carefully put the child's smile in my bag and left quietly.

I bought a magazine, which is full of decadent smiles of stars who are sought after by thousands of people. Their works only need to smile at the camera, no matter who they like or don't like on the other side of the camera, I rub this smiling face, which is still mechanical and stiff. I finally put it in my bag, hesitating and reluctant.

I entered a school, surrounded by laughter, which made me feel very warm. I walked to a small corner and saw a girl sobbing with a test paper and a boy beside her. "Don't cry, you didn't do well in the exam this time. Just try harder next time," said a young voice. "I believe you can." The boy smiled. The girl looked up and saw him smiling at her. She suddenly stopped crying and smiled. "Thank you," the sun suddenly became so bright. I carefully put their laughter in my bag for fear of damaging such a beautiful woman.

My schoolbag is getting heavier and heavier. When I opened it, I saw that all kinds of smiles inside had merged into a colorful rainbow. This is how rainbows are formed. Smile is a color. And this bag is my heart, too many things thrive in my bag, "because the heart is a warm and humid place, suitable for anything to grow."

..... Harvest a smile, just like harvest a rainbow, harvest a world that melts into itself.
