This is only 30 minutes train ride from Beijing to Tainjin but I decided to take the coach instead. Normally the travelling time for the coach is about 2 hours but on that day, due to an accident on the highway, I took 5 hours to reach Tainjin.
I only stayed in Tainjin for about 4 hours wondering around the shopping area, riverside and train station. Maybe I should visit Tainjin again on my next trip to Beijing and this time I will stay there for at least 2 days.
