How is the semi-trailer reversing technology tempered? Any expert advice? I am an old b, and I can't get started with this certificate.

It is not easy to master the reverse technology of semi-trailer. Some people choose to study with the car, but they can't learn for three to five months or even a year. They don't have so many opportunities to practice, and the master doesn't necessarily tell you everything. If you want to master this technology quickly, you can only find a professional teacher to learn and practice semi-trailer reversing technology professionally, so that you can learn to find a job and start making money in a week or so. This is a shortcut. I know a young coach. His teaching level is very high. As long as you are sure that you can do it with your heart, his coach car is the mainstream model on the market. After learning, you can work. You can go to him to practice the basic skills of straight line and side right-angle storage. There are also some bad habits of driving that I pointed out to you. I am a very responsible coach in Jining. If you want to learn by yourself, you can turn the steering wheel in the direction of the trailer from the mirror, and the car will straighten up and swing its tail wherever it goes. I feel that I can master it on the first day, learn to observe the movement changes of 8 points, and you will get started. If you don't want to go if you have a car, you can also give online guidance. Very convenient.
