What are you doing? But why do so many people learn in vain? That's because a so-called semi-skilled person who has studied in a technical school will drive his own car with a person who only knows theory. Therefore, employment is a problem. If you don't meet a good master, you will be annoyed that the excavator can't work, but you won't imagine that you can't. I have a bad conscience if I can't find a good teacher. Who will give something that is profitable and free to a person who is called a master by a stranger? But there are still good places. In order to satisfy all those who want to learn the real skills to support their families and give them a good choice in the future, please find a master, take students with your own excavator, teach you all the skills, let you practice on the construction site until you learn, and earn money as an apprentice, so that you can have security and income all your life. In this society, nothing is more reliable than mastering a technology. Come if you want to learn, and our family will try it for a month for free, including food and shelter.
