In the peaceful Qingping Village, there was a hard – working villager named Afu. He had a tricycle, which was his “capable partner”. Every day, it carried Afu around the streets to sell the agricultural products he grew. Recently, there was something wrong with Afu’s tricycle. Every time he went on the road, it bumped severely as if it was about to fall apart. Afu decided to go to the repair shop to replace a new set of leaf springs for the tricycle.​
The repairman took out a set of 700 main and auxiliary twelve – leaf leaf springs from a pile of parts and patted his chest to guarantee to Afu, “Afu, this is a good thing. With this installed, your tricycle will be brand – new immediately and run very steadily!” Afu looked at this set of leaf springs, skeptical, but still decided to give it a try.​
As soon as the new leaf springs were installed, Afu couldn’t wait to drive to the market. But not long after leaving the repair shop, he felt something was wrong. The elasticity of this new 700 main and auxiliary twelve – leaf leaf spring seemed to be too “unimaginable”. Usually, when passing through a small pothole, the vehicle just shook slightly. Now, as long as the road surface has the slightest undulation, the vehicle jumps up suddenly like a super spring. Afu was tossed around in the driver’s seat, holding the handlebars tightly with both hands and shouting, “What’s going on! Did I buy a flying tricycle?”​
Finally, Afu managed to get used to this strange bumpy rhythm and continued to drive forward carefully. When passing by the square in the village, a group of children were playing. They saw Afu’s tricycle bouncing around like crazy and found it extremely interesting. They chased after the vehicle, shouting as they ran, “Uncle Afu, your vehicle is performing acrobatics!” Afu didn’t know whether to laugh or cry. He wanted to speed up to get rid of these children, but the vehicle bounced faster and faster, and he couldn’t control the speed at all.​
When he reached the only way to the market, a dilapidated dirt road full of large potholes. Afu secretly groaned in his heart. He tried to drive through it slowly, but as soon as the vehicle hit those large potholes, it flew up like an out – of – control rocket. Once, the vehicle bounced so high that it almost hit a big tree on the side of the road. Afu was so scared that his face turned pale, thinking, “This is the end. I’m afraid I’m going to die here today!” The villagers passing by saw this thrilling scene and stopped one after another, opening their mouths wide. Someone shouted, “Afu, are you performing stunts? It’s too dangerous!”​
Finally, after getting through this dirt road, Afu was exhausted. His hat had been knocked off at some point, and his hair was as messy as a bird’s nest. He parked the vehicle on the side of the road, looked at this set of 700 main and auxiliary twelve – leaf leaf springs, which were the “culprits”, and sighed helplessly, “I thought I had found a treasure, but it turned out to be a ‘naughty ghost’!”​
Afu had no choice but to drive the vehicle back to the repair shop. The repairman saw Afu’s embarrassed appearance and couldn’t help laughing, “Haha, Afu, it seems that this set of leaf springs is not very suitable for your vehicle. Let me change it to an ordinary one for you.” Afu nodded repeatedly, “Hurry up. I don’t want to ride this ‘crazy roller – coaster’ anymore!”​
After replacing it with an ordinary leaf spring, Afu set off again. The vehicle ran as smoothly as if it was gliding on the ground. A relieved smile finally appeared on his face. This experience also became a topic of conversation among the villagers of Qingping Village during their spare time. Every time people saw Afu, they would tease him about that “crazy tricycle journey”.
