yeah, the language and even the writing. Also, I think some of those kungfu is filmtrick but Jackie Chan plays real most times

Except the fight on the air

Karate is Japnese. Kung Fu is Chinese ;-)
I think spoken Chinese is way easier than spoken Japanese, Chinese pronunciation is harder but the grammar is way easier. Both are equally difficult to read/write. #crossculture

Those cultures are confusing, Sometimes I need to sit and think hard to differentiate Japan from china.

I'm not quick in learning languages ,I doubt if I can learn these languages in
2 years. It's interesting to learn something new

A lot of Japanese culture derives from Chinese culture but it already has hundreds or thousands of years to become distinct. Japan adopted the writing system but the two languages sound totally different. #crossculture

There's a lot one needs to learn about cultures... Only a traveler can gain this much knowledge about other cultures
