A few days ago we went to visit the largest sundarbans area of Bangladesh. There we travel on the river and visit the place around. While traveling on the river, i noticed that some freight vessels were going towards the part via the river bank .The river is such a thing where this travel facility is very good. There was a time that everything transported from every trade system would have in the river . so in every country there was communication between the banks of the time.
We can say that large ships in the river are very useful because they do not waste their time and reach destination destination.
