Universities may be strong or weak, but which one is good or not is not determined by various rankings. You think Tsinghua Peking University is good, but personally, if I go to Tsinghua, it's definitely not a good thing. I'm not saying this because of sour grapes. Frankly speaking, when I took the college entrance examination, my first choice was to apply for Tsinghua, but I didn't get in because I didn't play well. I was very sad. The university I'm studying in now is inferior to Tsinghua in both hardware and software. However, I am definitely better off now than when I was in Tsinghua. In Tsinghua, I am definitely not outstanding because I am not particularly diligent or a genius. Then, I certainly can't enjoy all the benefits that I can enjoy in Tsinghua now. There are many good practical opportunities, and it's not my turn. Therefore, the best university is the one that suits you best, the one that you can make good use of and the one that you can accept. That's it.
