Tianjin is one of the four municipalities in China. Facing the Bohai Sea, the city serves as Beijing's vital gateway to the sea as well as the largest port city in north China. It is about 134 km (83 mi) from Beijing and it takes as little as 35 minutes to get to Beijing by bullet train. Once serving as a port for foreign concessions in the 19th century, Tianjin still has a lot of European-style buildings including the former residences of celebrities, industrial and commercial enterprise buildings, churches, and clubs on the Five Avenues. The Hai River flows slowly through the city and the towering Tientsin Eye spans over it. Taking a walk along the Hai River in the evening and overlooking night scenery from the Ferris wheel are must-do things. In addition, the endless delicious food in Tianjin is mouthwatering. Snacks like Fried Cake and Pancake Fruit that can be eaten on the street are the cream of the city's delicacies and the most authentic flavors. In recent years it has received more and more attention from visitors due to its illustrious historical heritage and other natural resources. Blessed with a variety of attractions, this is a good place to explore. There are also many natural scenes of beauty as well as great historical events.
