would be funnier if she replaces the Nihon character on Hetalia

This is too esoteric. One would have to be literate in Chinese but also be interested in what the Japanese think about what the Chinese think and also have to make the leap as a Chinese linguist into the dirty waters of Japanized Chinese language - they completely screwed up so many definitions of Chinese terms e.g. beloved spouse and cute versus lovable. It's all too much for non-native Chinese speakers and perhaps too much (as in too boring but in a tediously elaborate way) for native Chinese speakers as well. I shudder to think of those Indonesian caregivers educated in Chinese characters in Japan compared to the Indonesian workers in Hongkong who pick up colloquial Cantonese. Who would you rather be? There's no point in being both because that's like wearing one dry sock and one wet sock. I'm not going to bother to repeat any socalled Japanese slurs or learn new ones but baby, you can count on me protecting my kids from learning any Japanese because that is going to contaminate their Chinese language study. It's going to be hard enough restricting them to traditional characters for the first part of their education when there are so many Mainland Chinese products we will want to purchase.
