It is currently managed by the second generation Lin Yan Sheng and the third generation Lin Jian Liang. The floating fish balls are made from the belly and back meat of the fish. The fish meat is mashed into a paste, lightly seasoned, then shaped into balls and dropped into boiling water. They float to the surface when cooked, hence the name "floating fish balls." The broth from cooking the fish balls is thickened with sweet potato starch to create a clear, sweet, and delicious soup. A-Feng's floating fish balls are filled with milkfish, with no bones or thorns. The fish paste is made from milkfish, mixed with cilantro, ginger shreds, and black vinegar, giving it a uniquely fresh and delicious flavor. Address: 臺南市中西區保安路59號 Hours: 00:00–23:59 Tainan
