What is Asian culture?
I tell you, Asia is vast, i have travelled through most countries in Asia, lived there for over a decade and I can tell you it's diverse, there is no such thing as Asian culture.
Example, Thailand is completely different from it's southern neighbour Malaysia and Malaysia is completely different than Singapore (Although they would like to be like them).
But I do think there is some similarity in between cities/states/countries with a majority of "Chinese" people, for instance Singapore, HongKong, Taiwan and China.
