Is there anything interesting close to Tianjin train station within walking distance?

I remember that there are many interesting places nearby the station.
"Italian Style Street" and "Jinwan Square" are good choices for you. The first one is about 0.7 miles away. The other one is just about 0.4 miles away. And Jinwan Square is a large-scale shopping mall.
Besides, ancient cultural street is a Chinese characteristic street. It's worth to see. But the distance is about 2.8 miles. You can get to there by taking a taxi.
Hope you like. :)

What do you exactly mean the city center of Beijing?
Beijing South Train Station is about 8.2 miles away from the Wangfujing Street.

Hope helpful. :)
