I think this question is very representative. It is really tragic that a boy's poor math basically limits his study of natural science. You said that you like social science and want to work abroad. I wonder if your so-called knowledge of historical geography is foreign. Don't tell me what you see is made in China, then you will be tragic. I want to stay and work overseas. It is good to acquire a nationality and strive for a good imagination in politics and literature, but don't aim too high.
