The symbol of Gwangju takes the form of the sun and humans, the source of light and life, representing the aspiration for the world and the future, as well as the pioneering spirit of Gwangju, which literally means "village of light," or Bitgoeul. The circular shape represents the sun while the delightful curves symbolize the free human spirit.

The region had a close tie to Goryeo’s royal house over seven successive reigns, garnering the nickname ‘Childaeeohyang’ (meaning literally ‘seven-generation royal homestead’).
2. Busan Ports

Busan is the second largest city in Korea. Its deep harbor and gentle tides have allowed it to grow into the largest container handling port in the country and the third largest in the world, with potential for even more growth. Its natural endowments and rich history have resulted in Busan's increasing reputation as a world class city of tourism and culture.
1. Seoul Tigers or Seoul Wangbeomi
http://english.seoul.go.kr/gover/symbol/sym_05Mas.htm
Designed using natural brush strokes, the cuddly mascot tiger Wangbeomi was born in February 19, 1998. It represents citizens of Seoul with a strong spirit, open mind, lofty ideal, and light heart. Taking its image from a tiger character in Korean folktales, the mascot is also a good match for the city's official emblem.
"Wangbeomi" is a compound noun made up of "wang" (king, chief, head, or very big), "beom" (tiger), and "-i" (a noun-derivational suffix). The big-eyed tiger's name best befits the image of Seoul, a global city as well as the capital and the largest city in Korea.
Enough Korean history for, time to get back to work, hope this helps a bit...
Cheers!
