Chinese is the most superior and have 더 많이 "blocky" characters. Japanese is the 더 많이 technological of them and have 더 많이 "cutesy" characters. Korean...they sing pop...I guess....they have "circular" characters.
So, image below is in this order: Korean characters, Japanese characters, and Chinese characters.
I dont know a lot about the languages, only about their appearances. I think the korean and the japaneses eyes are a bit 더 많이 open than the of the chinese. And the names are a bit different too. (So far I know) Exp: Chinese: Xiaomeng Li Japanese: Yuri Ishiyama Korean: Park Jae Sang
