Hello, if you want to apply for the Yangtze River Delta, I suggest you apply for schools in Jiangsu (of course, there are also good schools in Shanghai and other regions, but I don't know much about them personally, so I say so). If your grades are quite good, you can be admitted to Nantah. If you don't feel sure, Suzhou University and Yangzhou University are both very good.

As for the major, the history major is a national unified examination, which is relatively more difficult (the unified examination means that the independent proposition of the university is not a national unified examination paper, so it is difficult to grasp the key points), and employment is relatively limited. Compared with political economy, it may be a little better, but I personally think that interest comes first, or I care about what you prefer.

Of course, you are just a freshman. Personally, I think you should study the courses of this major first. Freshmen and sophomores can read some extracurricular books according to their own interests, really know what they want to learn, and then work hard for the postgraduate entrance examination in the third year.

Finally, I hope you will succeed in your studies!
