We can go anywhere we want to visit with the advance technology that has been provided by the technology of transportation. However, such visit will only be on the surface level if we cannot know more about the people who live in there.
If you are up to another country and blending with the people who live there, you need to adjust yourself with the new culture. On the first level, you need to do some research on the culture.
The research can be done by seeing at the perceptions of the people there on outsiders. Then you can also look at the typical foods they are providing, the social customs, etc.
