What? I don't know Chinese!! Oh, my god! I can't believe it, I am a chinese person, but I really don't know Chinese, it's so funny. This week, I found there is a place named "Global village" hunting for a chinese teacher who can teach foreigners, I laughed and went into the room, the manager said I should have a test, so I said OK at once at the same time I laughed in my heart and think it easy for me---a chinese person who has spoken chinese already for 30years, but in fact I was disapointed and sad. He asked me what's the difference between 刚才 and 刚刚, between 经常 and 常常, between 适合 and 合适, and so on. Suddenly I felt sad, because I don't know, I really don't know, in fact for me---a chinese person who has spoken chinese for 30 years, I think there are not any difference between them, even we chinese persons don't care about that meaning. From now on, I was disapointed and sad that I can't learn English very well and I also can't teach chinese. Oh, my God! Am I a fool? What should I do? What language should I speak? I doubt I haven't language ability, Yes or No!!
