First of all, to correct you, investment banks don't only accept Peking University, Tsinghua and Fudan Jiaotong University. Perhaps some top investment banks have such special requirements.

I don't know if you are an undergraduate or a graduate student. If you are an undergraduate, it is better to study at least as a graduate student according to your wish to apply for a foreign company or investment bank. In addition to the resumption of diplomatic relations between the North and the Qing Dynasty, it is better to be admitted to the National People's Congress, the central government, and Shanghai University of Finance and Trade.

As for textual research, I suggest you base yourself on this major. Among them, accounting qualification is the basic qualification for accounting, and the content of certified public accountants is relatively high. These two certificates should be considered emphatically. If you pass the CPA certificate, I believe your job search will be much smoother.

If you have a strong desire to enter the securities industry, you can also consider the qualifications of securities practitioners and financial planners.
