What are the places worth visiting in Tianjin?

I think Tianjin is an important city in the north of China, with rich history and culture and unique urban scenery. Eye of Tianjin, Fifth Avenue, Ancient Culture Street, Haihe Italian Style Street, Porcelain House, Beiyang Navy University Hall, hometown of Tianjin, Tianjin is a charming city. These must-see places not only show Tianjin's unique urban scenery and rich history and culture, but also bring different travel experiences to tourists.
