What are some of the ways that people celebrate the "Jindo's Sea Way" festival in South Korea?

Context: A medium-sized hunting dog breed called the Korean Jindo Dog originates from Jindo. It is known in Korea for its fierce loyalty, attachment to home and hunting abilities. Since 1936, the dog is considered as a national cultural legacy and has been protected during the war times. There is a Jindo Dog Research and Testing Center on the island.

The tide-related sea level variations result in a land pass 2.9 km long and 10–40 meters wide opening for approximately an hour between the main Jindo island and the small Modo island to the south of Jindo. The event occurs about twice a year, around April–June. It had long been celebrated in a local festival called "Jindo's Sea Way", but was largely unknown to the world until 1975, when the French ambassador Pierre Randi described the phenomenon in a French newspaper. Nowadays, nearly half a million foreign and local tourists attend the event annually. It is accompanied by local festivals which include Ganggangsuwollae, Ssitkim-gut, Deul Norae, Manga, Jindo dog show, Buknori and fireworks.

The island has three art galleries, Sojun, Namjin and Sochi, containing collections of painters who worked here over the past centuries.

Answer: Almost half a million people travel to Jindo annually to celebrate the "Jindo's Sea Way" festival each year. Celebrations include traditional circle dancing, farmer songs, fireworks, and a Jindo dog show.
