Your own name

I've learned Japanese for quiet a long time. There are many interesting Japanese teachers I met. Here's Takahashi sensei (the sound of "teacher" in Japanese).
He's such a funny old folk from his talking and behaves. Although he's a pure Japanese (who actually came from Japan) but he can speak frequent Chinese. He concentrates on his teaching very much, for example: he spent 5 to 6 hours just to translate a paragraph of NHK news for his student. I can see his self-esteem from his attitude of teaching. And proud of being a Japanese.
One day after a normal teaching, Tuesday evening. We just finished a lesson of how to describe a dangerous situation in Japanese. Usually at this time, teachers would tell a joke or say something funny to relax his student, he did not. He told as "Save your name."
"Everyone has the original name gave from his or her family. You should respect of it, instead of abandoning name when you meet someone from foreign country." That is, he suggested that we holding our name and using it. For example, my Chinese name in Romanize is "MING-CHIA KAO", but usually when I introduce myself to a non-Chinese, I would say "My name is Eric Kao." Takahashi sensei wanted us to think why we use a non-native language to tell other who we are. We should respect our own name by using our original name and they should also respect us in the same way.
My family gave me this name to represent myself. I am proud of saying this name to others because that's me. The real "MING-CHIA KAO." Maybe someone would say that it is hard for foreigners to understand. But in my opinion, we sometimes confuse with foreigner’s last name and we sure to understand that and respect of that (the cackle-pronounce foreign name). And they would and should respect our own.
I think this is a good thought of maintain our culture, by saying our real name, and a practical way to do.
By the way, my takahashi sensei, the Japanese old guy, insists we called him in Japanese. Why? After all he's a Japanese teacher.
