Dear Dora
I remember my young days in university.I had a Chinese girl class mate who came from Beijing.
She is so intelligent that she can speak Japanese,English,as well as German,and off course Chinese!
I like learning languages too and I try to master French as well as English.
In Japan,Chinese is popular to businessman.So you will find a lot of books that guide to master Chinese in Tokyo bookstores.
I afraid your majyor subject is too difficult for me to understand.
But I will try to know that if possible.
Do you make any foreing friends in EnglishForum?
