Tianjin to Mutianju Wall

Is is possible to travel from Tianjin port to Mutianju Wall and back in one day? Thinking of seeing wall for a short time and a short stop in Tiananmen Square. How long would this take and does anyone recommend a private tour who would do this.

I personally would look at a tour company, it is a long way, On your own, changing trains to taxis waiting for transfers etc will eat into your day. Use google to check times and distances,

Good luck
