there's also alotta anti-japanese products psychology in China, so that may explain why topre isn't as popular,,, ALTHOUGH japanese pr0n is somehow excluded from the racism.
True, but not 100%. Japanese products are still deemed as high qualities. FILCO is still worshiped as top tier keyboard over other competitor.
I believe topre's price is the main reason that it isn't popular.
For the pr0n part, can't deny it. I came from a multiracial country(which also being ruled by Japan b4) and I had seen that those foreign Japan stuffs(JAV, JManga, JAnime and so on) are actually promoting racial integration effectively than any other mean.
