L'amore e cieco

When you say MP3, how do you say?
When you say P10, how do you say?
When you say T7, how do you say?
Have you ever notice the way you express them?

I have been corrected the way I said by my friends who are bilingual in Chinese and English.
The way I said is so annoying that they can't stand.
In Taiwan, we usually say p七.
No one will say you are wrong.
Taiwaneses usually express them in half English and half chinese.
However, if you say it the same way in America, even Chinese speakers will feel weird.
Possibly,they need ten seconds to figure out what you said.
In the United States, everyone says p seven, even Chinese speakers.

I don't want to say "p七" is a wrong way to say.
But I have to admit that "p seven" sounds more professional.
In conclusion, I believe, "p seven" is what the name designed to be called.
