Wooden carts are rare now, so it seems time to write something. Otherwise, future generations may only know the carriage on TV, and they don't know that there are human carts. Nowadays, even in small villages, as long as there are tractor roads and even if there are no motor vehicles, most of them use pedal tricycles, which is labor-saving and convenient. Nowadays, people who drive cars to farm are often seen, and the times have really improved. Maybe cars will be eliminated soon, and everyone will fly freely in the sky like dragonflies. When we think of it, our younger generation will say, "Think about when Grandpa used to drive his father to school with gasoline every day ..." As we say to our children now, "When there were no roads and cars ..."

From the course of human body liberation, the application of the wheel is a great revolution, which, together with the revolution of communication tools, has almost become a portrayal of technological progress. From the course of my personal family, the most intuitive embodiment of every economic leap is also the change of wheels.

My first wheel revolution was to buy the wheels of a scooter. It was the 1990s, ie it was far behind others. I used to be almost shoulder to shoulder, hand in hand. Even if it is far away, you should carry the burden back and forth. It seems incredible to think about it now, but it has been a reality for thousands of years. Occasionally, for important farming, such as harvesting rice in autumn or cutting firewood in the distance, borrow a scooter from others. At that time, the frames of people with cars were usually standing by the wall of the house, which was easy to see. Every time because of face, I have to borrow it from my close neighbors. You must use it very carefully, especially if you don't rub the rubber edge. At that time, I dreamed of having a scooter at home, but in that era when I didn't have enough to eat and put on, and I couldn't even pay the tuition, my family couldn't afford scooter wheels for a long time, just like now I have to buy a plane.

Buying scooter wheels is almost a landmark event in my family, just after my first job. I clearly remember buying a car. I took the shuttle bus to the farm tool shop in the county early in the morning. Without bargaining, I stood by and watched the boss connect metal wheels with bearings and outer rims, and then put on tires. In order to facilitate transportation on the passenger bus, connect the two wheels and the connecting shaft between the two wheels after returning home. We hired an uncle who knew simple carpentry, made a frame out of his own wood and became the "owner" from then on. Later, I bought bicycles and cars one after another. In terms of importance, scooters should be no less than these two.

Heavy, slow, accompanied by sweat and blue veins are the indelible marks left by scooters in my mind. It's a little worrying to see a scooter full of heavy objects driving on a hillside. The elbows in front of the car are tightly clamped with the arm, the body plate leans forward, the head stretches forward, the veins stand out, the legs push back and move forward in an S shape. The steeper the ramp, the lower the posture until the body panel is parallel to the road surface. The pushers at the back also tried their best to grab the frame, resist the goods at the back of the car, and try their best to lower their bodies ... Climbing a long slope, everyone was sweating, blushing and panting.

When we were young, riding a car was a luxury. It is a pleasure for me to sit on the bus and smell gasoline. Going to the county seat now is like going abroad. Generally, children take the scooter first and then the bus. Sometimes adults take their children to work in the mountains, and sometimes they go to chop wood with their partners. They sit on scooters and enjoy "sloping". "uphill" is to slide the car down the slope, which is the most enjoyable and exciting thing to pull the scooter. The car pushed people away without any effort. Every time we reach the top of the slope, the people behind the cart climb onto the goods and pull the rope tightly. A superb driver can keep his car balanced and slide freely by hanging himself. A wooden stick tied to the back end of the bottom of the plate frame is the brake. We call it "tail drag", which slows down by the friction between the stick and the ground. Now imagine that this is extremely dangerous. Fortunately, the road at that time was a gravel road, with great friction and bumps, and the car could not get up quickly. Nowadays, cement roads or asphalt roads never dare to do this, and they have to fly off the road ... Besides, there are too many cars coming and going now, and it can't tolerate such turtle speed.

Going uphill seems simple and labor-saving, but it is completely technical. Make sure you can control the car. Superb drivers can also sit on the side of the car, slide down the road completely by scooter, and occasionally use the pedal to control the direction. I once saw a scooter pulling bricks in the city. The coachman sat directly on the handlebar and drove at high speed on the flat ground beside me with an empty car. This kung fu must have been practiced in the countryside.

At that time, it was very common to use scooters, and occasionally there were incidents of overturning and injuring people, but most of them were only flesh wounds and few died. However, in recent years, I heard that many villagers died in accidents caused by riding tricycles or motor vehicles. It may be because the speed is too fast and the control is too fast, but the consciousness and matching can't keep up. This is also a heavy lesson!
