On the one hand, many TV shows create a good image in the eyes of the viewers and the drawbacks are often ignored. Nowadays, to promote tourism, countries always want viewers to gain insights into various cultures through interesting travel programs, but sometimes they make untrue documentaries. For example, some programs always introduce that people in a specific area are hospitable and friendly, but the truth is that tourists are ripped off by locals. In addition, a country always has many unique aspects of culture, cuisine, and so on, which viewers cannot grasp through programs.
