What is culture?

I have been thinking what is culture in the Singapore context.
A very good and general term you might tell is Multicultural society.
But what exactly is multi-cultural?
In terms of races, religion?
According to Paul Du Gay, a sociologist, it is a set of shared practices under a common interpretative framework.
Shared practices that we as Singaporeans do know and immerse into.
What is it?
Languages like Singlish and English?
Food like Hainanese Chicken rice, laksa, roti-prata?
Shared interest like 4D?
I don't know. Frankly speaking, this question has been haunting me since my lecturer ask it.

Then she went on to ask what is culture industry?
Of course a standard and lame answer would be an industry that produced culture lah?
A rather oxymoron term.
Under Singapore's interpretation, creative industry like animations and special effects are under it.
That make me even more confused.
Is a lot of people under this broad framework?
Nah, god knows if people know there is a creative industry if not for the today's news that government going to pump in $1B (you see it right) into this industry that has great potential.
Haha...
To me culture is simple. There is no high arts like Mozart or popular culture like boybands.
As long as people enjoy and interpret in their own ways, it is culture.
So to me:

Culture is an art.

Culture is about creativity.

Culture is a bond that bind people together.

Culture is not really about money (although nowadays culture = $$$)

Culture is what makes a group of people happy.

Culture is what that make people participate and immersed in.

Culture is what you can share and people understand it.

So another question comes, do you believe there is a global culture?
I would say not really. Some practices happened to be coincidentally similar. Others are created by you know, TMNCs.
I would say everything is somewhat unique in certain way though you might say well people imitate others.
Well, imitation cant get you anywhere. Unless you modify it. By modifying it, it is unique.

Well, some thoughts here....

hope you dun mind my rambling.
