   Fengcheng River is a 6650-meter-long moat(护城河)that protected Taizhou from enemy. Currently, the Fengcheng River Scenic Area has become a natural area of the modern city.
   The four cultural treasures of Taizhou——history, local opera, customs and business—— can all be seen along the river. Taizhou Old Street lies on the east of the Fengcheng River Scenic Area, offering choices of restaurants and local specialties（特产）. The Peach Garden is also along the river, with blooming peach trees. The Sea-watching scenic area is also on the river front, among many other attractions. To have a holistic view, you may be interested in taking a night boat around the ancient moat and the ride shows Taizhou’s culture.
Fengcheng River Night Cruise（巡游）

   This night cruise takes you an hour long ride on the city moat. The boats are classic ones that seem to be floating houses. While on the boat you'll be able to enjoy local snacks like sesame seed biscuits and tea. Along the river side, local dance and song groups perform, creating the perfect mood for the boat ride. Also, the scenery formed is wonderful. The Sea-Watching Pavilion with shining lights is beautiful in the evening.
