Are you a foreign language major? Then I suggest reading the English version of Ross's Corporate Finance. Have a general understanding of financial management. To be honest, I'm not very supportive of watching currency wars. The words of one family are too serious to represent the knowledge of economics and finance at all, and they are too narrow. The Economic Observer is a good choice. I suggest you read The Economist. The Wall Street Journal and the Financial Times (British, not domestic) are believed to be of great help to you.
