Not bad. I have known several companies before. Some are more expensive, and some have theoretical courses. I think it's all ridiculous. Technology is nothing else. You must learn through practical operation! You think it's like a child going to school! Not to mention video learning, children have to practice when they learn the piano! Green is more practical, and it is all practical training. I have been working for six or seven months, and now my monthly income is more than 5000, which will definitely increase.
