Chen's Shop is a General Store in Harvest Moon: Island of Happiness. The day after you arrive on the island, Chen will move in the Island with his son Charlie. The shop is also the place where the family lives. Chen's shop is open Saturday through Thursday, from sun up until midnight. On Fridays he travels off the island and does not return until 3:00 pm. You can also sell items to Chen. You have to hold the item in your hands, then tap Chen to bring up his inventory. If you scroll to the bottom of his items, you'll find the option to sell.
