I want to ask to do equipment maintenance and management is good, there is no development

Equipment maintenance and management can learn, this is a technical job, not only will not depreciate with age, you can say will appreciate.

This aspect of the market is quite big, our factory out of the equipment to go to the field are generally looking for local construction team.

You can work towards this. In the future, you can specialize in this industry. And it is much better than sitting there and drawing.
