我１９８１年考上清华大学物理系，近代物理专业。当时整个社会都有一种很偏激的观念，念书是惟一重要的事情，念书最好的学生就是好学生。 也许现代考试制度不太适合于我，我在严重的竞争压力下花的时间很多，效率不高，成绩虽然在班上总是前几名，但一直处于艰难的竞争之中。 I was admitted to Department of Physics, Tsinghua University in 1981, modern physics. At that time, there was an extreme concept in society as a whole. Studying was the only important thing. The best students studying were good students. Perhaps the modern examination system is not very suitable for me. I spent a lot of time under severe competitive pressure and inefficiency. Although the results are always the top in the class, I have been in a difficult competition.
