Author met a young woman at the seminar.She learned speak Mandarin Chinese was very difficult for her.She learned it for two years.Only mastered some basics for her.Author said to her learn Mandarin Chinese don’t difficult.At least for a Westerner.Only have a few months.She heard it and look at me like a slightly mad.Author rather than get into the argument so write this”The third ear”.Of course. I agree with the author’s reason.if you into the country to learn the country language.So you apply the author method of learn a new language.you can achieve your goal for master a foreign language.
