my idea about the definition of culture is the complex structure characteristics of a particular group of people, defined by everything from language, religion, cuisine, social habits, music and arts. it can learn from generation to generation.About the example from my own cultural,Pointing is unacceptable in Thailand.We don’t point at monks or pictures of any of the Royal Family, and as a general rule don’t point at people to make reference to them. If you need to point someone out, instead of extending your finger, bend your hand downwards with your fingers toward the floor and your palm facing upward.
