I regret to study Chemistry, although I still love Chem now. Chem as major in Uni is one of four most futureless majors in China (The other three are Biology, Environmental Science and Material). And now I am considering how to make decisions wiser

回復 @淺風仁櫻：That's true. Human beings can get the result only after trying. This is an eternal dilemma for human beings
