How much does it cost to drive an excavator for about a month?

I am working here in Gansu now, with a salary of 7000 yuan a month. You have to be able to bear hardships in this line of work. Working on the construction site is sometimes boring and needs to be adjusted by yourself. And the most important thing is how your skills are. After I started my new study in Luoyang, I earned more than 3,000 yuan at first, and now I am almost a master by practicing on my own.
