1. At present, the college entrance examination is in the form of checking scores first and then filling in volunteers. I think since you have been admitted to the university and your major is clear, it is certain that you chose this major when you filled in your volunteers. From this point of view, I think you still like or yearn for this major type, so since you chose it, I don't think you have any regrets. Unless you think you have a major you want to develop.
In fact, for every industry, as long as you learn, everything will be useful. As the saying goes, the 360 line will be the best. I also studied Chinese language and literature. I graduated in 1999, worked as a tutor for one year, and then went out to work by myself. Now through my own efforts, plus what I learned in school before, I have developed very well outside. So personally, I think there is no difference between good and bad things. As long as it is what I like or what I am good at, I can try.
3. With regard to the development of this major, because I am also studying this major, I have some experience that there is still room for development in this area, such as: I can try to be a teacher or come out as a senior secretary and senior manager in the future ..... all these aspects are OK. The key is how to apply what you have learned.
The above are just some of my personal views and opinions, for reference only, I hope to help you.
