The other two are good. Every industry has its prospects and learning knowledge. Internet companies only say that they should pay more attention to the Internet, and all aspects should be biased towards Internet products and operations. But traditional integration also has some connection with the Internet. You can learn wiring system integration, and then you can be an assistant if you are interested in the Internet. The latter is a technical activity, and entrepreneurship is also possible. The former has a certain imagination, contact will have more ideas and ideas, enrich all aspects of information, and find a piece that suits your interests from practice. Then you have the ability, you can start your own business after you have completely modeled it. Both are fine.
