My favourite city is Seoul.Seoul is the capital of South Korea and is located on the Han River in the country's northwest. The city is situated about 50 km (~30 mi) south of the North Korean border, also known as the de-militarized zone (DMZ). Seoul is a city with ancient history, the area of Seoul appears in history as early as 18 BCE, when the kingdom of Baekje founded its capital, Wiryeseong, in what is now southeastern Seoul. Modern Seoul descends from a city called Namgyeong, built during the Goryeo era, which then became the capital of the Joseon dynasty in 1394. Seoul has been the capital of successive Korean nations ever since.[2]Designated the status of a Special City, Seoul is administered directly by the national government.

　　With over ten million people, Seoul is South Korea's largest city and one of the largest cities in the world by population. Covering an area of only 605 square kilometers, smaller than New York City or Tokyo, it is one of the world's most densely populated major cities.

　　The Seoul National Capital Area, which includes the major port city of Incheon, has almost 23 million inhabitants making it the second most populous metropolitan area in the world, after Greater Tokyo. Almost half of South Korea's entire population lives in the Seoul National Capital Area, and nearly one quarter in Seoul itself, making it the country's political, cultural, and economic center, as well as a center for international business. The rapid economic, social and technological development of the city has played a key role in South Korea's development, and has been referred to as the "Miracle on the Han River".

　　Seoul hosts more than three million registered vehicles and widespread traffic congestion is common. In recent years, the metropolitan government has undertaken extensive clean up of the city's air and water pollution. The revival of Cheonggyecheon, a stream that flows through Seoul city center, was a recent major urban beautification project.

　　我最喜欢的城市是首尔。首尔是韩国的首都,位于汉江在该国西北地区。这座城市位于以南约50公里(~ 30 mi)朝鲜边境,也被称为de-militarized区(DMZ)。首尔是一个城市,古老的历史,首尔的区域出现在历史早在公元前18,Baekje王国建立其资本时,Wiryeseong,在现在的首尔东南。现代首尔是一个城市叫Namgyeong建立了该时期,然后于1394年成为李氏王朝的首都。首尔已经连续朝鲜国家的首都。[2]指定状态的一个特殊的城市,首尔是由中央政府直接管理。

　　超过一千万人,首尔是韩国最大的城市和世界上最大的城市之一,人口。占地面积只有605平方公里,比纽约或东京,它是世界上人口最密集的大城市。

　　首尔国家首都地区,其中包括主要的港口城市仁川,拥有近2300万居民第二世界上人口最多的城市,在大东京之后。几乎一半的韩国的整个人口居住在首尔国家首都地区和近四分之一在首尔本身,这使得该国的政治、文化、经济中心,以及国际商业中心。经济、社会和技术的快速发展城市发挥了关键作用在韩国的发展,和被称为“汉江奇迹”。

　　首尔举办超过三百万注册车辆和广泛的交通堵塞是很常见的。近年来,市政府已开展了广泛的清理的城市空气和水的污染。清溪川的复兴,一条小溪流过首尔市中心,是最近的一个主要城市美化工程。
