Grocery store and seaside store, grocery store road: when you leave the pasture, go up, go straight, you can see the library, and then go right. The grocery store is near the fork in the road, with the village head's house on the left and the hospital on the right. You can look at the sign in front of the building to confirm that the opening time is recorded in addition to any store. I don't need to say anything about the seaside, but make sure that Huo An has appeared and the opening time is late. Grocery stores start selling seeds of three seasonal crops in spring, summer and autumn, but if these three crops are delivered in sufficient quantities in each season, you can buy a fourth hidden seed (which is sold in all three seasons).
