D1: from the train station out, first to the station square (by the Haihe River), take a look at the other side of the river, Jinwan Square, European-style buildings, although it is a new building, or very beautiful, and then walk down the river to the right hand side (the north, if you can discern the direction), not far from the liberation of the bridge (formerly known as the French bridge, across the bridge is the original French Concession), at this time, you have two choices, over the bridge! Visit Jiefang Road European-style buildings (all more than 100 years), or continue to walk down the river, in front of the Dagu Bridge, Italian-style area, Bei'an Bridge (very beautiful, although it is a bridge over the Clone Seine), Austrian-style area, Jintang Bridge (liberation of Tianjin's meeting place), across the Jintang Bridge is the ancient culture street. You can also continue up the river, Lion Grove Bridge, King Kong Bridge, Yongle Bridge (where you can visit the Tianjin Eye Ferris Wheel and the Great Compassionate House). At noon, you can go to Food Street, and in the afternoon, you can go shopping on Heping Road and Binjiang Road and visit the Five Avenues. These places are very close to each other, the family suggests taking a taxi, should be about 10 yuan is about right. Recommended a restaurant, the five avenues on Dali Road, there is a meeting Fang Lou Halal restaurant, is also a long-established, next to the Mutual South Park, I think than Hongqishun strong, Hongqishun service is too bad.
D2 recommend two places to see the sea. The beach is not to go, artificial beach, in fact, is a large swimming pool. Tianjin Port has a tour of the port of the cruise ship, take a look at the Tianjin Port Terminal, if the first time to see tons of giant ships, or very shocking. Another place is the aircraft carrier Kiev, if you like the military, this is a must-see, this is a real aircraft carrier, China has only two (the other Minsk in Zhuhai). After the tour, you can take a train from Tanggu directly back to Beijing. I'm not familiar with the route in Tanggu, so look it up yourself.
