Oh. you mustn't worry, every nation has their own culture. There are the differences in every culture. Once I knew a chinaman, he was amazing, he was a real friend to me, but he died, he was very ill, but wise, I know now many things he showed me, he taught me…

and I'm very interested in your culture…  

Well 2 weeks ago I started learning chinese in chinese culture centre and most of the people says Its not that different from my country except foods of course most of the people who goes to China from here were complaining from foods but rest is not that bad I think..  

By the way I need to learn more about chinese culture what can you tell me about your culture?
