It is my honor to be adimitted to WISE,because I can follow a famous professor Hong,yongmiao.Although I am a freshman in economics or econometrics,I believe that I will be a young economist in a not too long future.It is a challenge to catch up with the level of foreigners in economics,so all of us,including freshman and economist,should pay attention to academy but not others,real economics but not marginal economics,such as political economics and history of economics。
