Among the experiences of traveling or living in Seoul, the most impressive thing is undoubtedly the friendliness and enthusiasm of the local people. Whether asking for directions on the street or seeking help at shopping malls or stations, every person I met showed great patience and friendliness. It is particularly worth mentioning that during my time at Chingu Mobile, the staff there gave me great help. They are not only kind and friendly in attitude, but also provide meticulous and considerate service. They always answer all kinds of questions with a smile on their faces. Even when I couldn't speak the language or express myself clearly, they never showed any impatience. This considerate service made me feel at home and left me with a warmer and deeper impression of the city of Seoul.
