A few years ago, my tutor was an American, and he shared his experience of learning Chinese. He said: When he came to Taiwan. He doesn't understand Chinese. Until a day he found a girl, the learning curve was straight up and as jet-flying fast. He witnessed the power of true love. This couple were a happy ending.

After the teacher shared. Students we laughed and self deprecates said: "This is why we have studied English for a long time and still not good". Ha ha.

PS. I have studied English for 15 years.
