One year has passed since the North shelled Yeonpyeong island. North Korea can still be seen with the naked eye over the horizon and the horror of that day is still fresh in people's minds.

But as they move on, most of the island's residents have resumed their daily routines. Oyster harvesting starts this month, and 65 percent of the islanders rely on fishing to make a living.

Some older residents sit outside their homes cleaning the oysters they, or their grandchildren, have collected from the sea. Others turn to crab fishing, which is a major income earner for locals. This is considered the best month to catch the crabs, but the fishermen who routinely load heavy nets onto their boats at this time of year and head out to trawl for them have reported below-average catches due to warmer temperatures this year.

Meanwhile, around one in 10 residents works in the service sector, with numerous guest houses, motels and restaurants dotted around the island. They report a slight increase in interest in the barely known tourism resource since the shocking incident late last year, and say that life is slowly creeping back to normal. But at least one restaurant owner says it still hurts to think about that fateful day one year ago when the attack was launched.
