In a bowl, combine char sui, shrimp, green onion, parsley, and oyster sauce; mix well. Pinch dough into 1-inch balls. Flatten each piece with your fingers. Place a heaping tablespoon of filling in center of each piece. Mold dough around filling, sealing edges to form a ball. In a wok or skillet, heat oil to 400° F.
