After graduation, if you have work experience, just choose what you like. As long as you are proficient, you can tell others. This requires learning more, asking more questions and accumulating more practical experience in their own jobs. After all, people don't want to listen to books or look for them on Baidu. Everyone likes to listen to some practical things, so we should observe and think more.

In short, don't worry about anything. Pick one you like. As long as you are proficient, people looking for you will line up.
Come on ~ peer!
