Describing cultural differences! Well,I think the culture of each nation is defined by taking customs and ceremonies of that nation. So it's true that all of the people around the world haven't the same culture for example in my country Iran,people have to observe Islamic cover while in other countries observing Islamic cover isn't obligatory. Also in my opinion, the culture of each nation returns to the past,it means usually our culture is the same with our ancestors' culture. [Thank you for reading my text ]
