The special geographical environment also makes Wuhan to be a metropolitan city of bridge. One bridge after another were built, which not only changed the pattern of the city, but also ushered in the era of "crossing". They crossed two rivers and proved the old saying that has not changed for a thousand years: The three towns are vigorously woven into a trinity, and the rivers endowed Wuhan to become a metropolitan city of bridge. Including the Shuangliu Yangtze River Bridge under construction in Wuhan, there are a total of 12 Yangtze River Bridges. Before the Yangtze River Bridge was built, it was almost normal for people in Wuhan to cross the river by ferry.For old Wuhan, ferrying between Wuchang and Hankou is very popular. Ferry used to be one of the most important means of transportation connecting the three towns of Wuhan. The ferry in Wuhan has gone through a history of more than one hundred years. The wharf culture is a kind of feeling deeply rooted in Wuhan people. In river city Wuhan, there are indeed extraordinary people who can swim across the Yangtze River. the real purpose of crossing the river is for people to express their awe of the Yangtze River and Han River in this way, and at the same time to call on more people to protect the Yangtze River and Han River.
