Before answering the question, let me tell you this question is too broad. At least, I can define one of the most important things in my culture. First of all, my country has twelve millions inhabitants. Nearly twenty diffirent ethnic group live there. Speaking of culture and custom, I can talk about the marriage for example. Getting married in my country require two main step. The first is the traditional wedding, and the last one is established to the municipal building. However, it is not compulsory to follow these two steps, but one of them at least.
