A cartoon Jewish man might often be depicted with a distinctively styled hat or yarmulke. He might also have certain facial features like a prominent nose or thick eyebrows.
I'm not sure. It's possible that Cartoon Cat has no significant or well-defined relationship with China. It could be just a concept brought up without any substantial connection to the country.
I think it could be because it's an easy way to get a strong reaction from the audience. It's kind of a wild and unexpected element that makes the cartoon stand out, but not everyone likes it for sure.
I think 'Ao Haru Ride' could be a good choice. It has a comparable focus on the emotional journey of the characters and a similar style of storytelling.
