Any transport from the cruise port, Tianjin, to the great wall? Any recommended ways ? Thanks

I hope my answer is not late for you.
There is a section in the city of Tianjin, I think you can go there first. That section is called Huangyaguan.
From the port, you can take a taxi to reach Citizen Square and change local Light Rail to reach Railway Station where you can change to subway line 3 to reach Tianjin North Railway Station. Then you can take a taxi to reach Hebe Bus Station to take bus for Jixian. Then you can find many buses for Huangyaguan at Jixian.

If you want to go to Badaling, you can take the same line to reach Tianjin Railway Station to take bullet trains to reach the Peking South Train Station where you can find S2 bullet trains to reach Badaling.
