Nanfangao, located at the south of Su'ao Harbor, is an important foundation for coastal and near-sea fishing boats in Taiwan. The catch is amazing here so it is one of the three chief fishing sites. There are three harbors and fish markets with different functions and characters here. The First Fish Market opens at 2 o'clock every afternoon. The fishermen's association hosts the auction. The Second Fish Market opens from 3 o'clock to 5 o'clock every afternoon. Fishermen sell their catch in person. Harbor Road beside the Third Fish Market is full of seafood restaurants and specialty stores. It is the place crowded with tourists.
