The first one: in everyone's mind, learning hydropower technology is to find a friend, a relative and a master, and then learn. In this way, it is simple and there is no cost. The key is income. Many brothers, in this way, started their own plumber career.

The second one: find a hydropower training school. Generally, tuition fees are relatively high, all of which are thousands. Many brothers are unwilling to spend this money. I would rather work as a coolie and grind slowly, believing that I can and can learn, so many hydropower training schools are inseparable, as simple as that.

Third: Tencent's course "Practical Techniques of Well Diameter Hydropower" starts in 2 months and takes over the work by itself.

Hope to adopt
