I don't know about Guiyang, but Dana is the largest training institution at present. IT's just that for IT training institutions, the level of each region is different, and the quality and types of courses are different, so the focus of your question is really that each region is different. Guiyang is the place where I study big data strategically, so I focus on big data and artificial intelligence. I have a good foundation and I am eager to learn. I can audition. I don't recommend registering immediately. I hope to adopt it ~
