Dịch bài sau : Seoul is the capital of Korea, the largest city in Korea, and its population is one of the largest in all over the world. More than half of the Korean population is concentrated here, and it makes Seoul a cultural and political center of Korea. When anyone mentions Korea, a lot people immediately think of the K-pop music market and the internationally popular artists. If you are a big fan of K-pop, some big entertainment companies are unmissable places to visit. By stopping by there, we can see and buy idol-related products; and if we are lucky enough, we can meet and get their autographs when they come by the company. After meeting famous people, we can visit the palace or the historical museum of Korea. Besides sightseeing, eating is also important thing that we should do in Seoul. Seoul is home to almost every traditional Korean food such as kimchi, sticky rice cakes, rice wine, soju etc. It is nothing more interesting than eating steak with a bowl of hot boiling kimchi soup, and enjoying some glasses of soju in Korea's cold weather. Besides, Seoul is also a city of sport since it hosted the Asian Games 1986, the 1988 Summer Olympics, and this was also one of the host cities of the 2002 World Cup. There are a lot of special things about Seoul that have not been mentioned yet, but it is still enough to see that Seoul is a lovely and worth-living city.
