The boat arrives at the bridge is naturally a common saying. It is a common saying that was created by the masses in Chinese vocabulary and spread in the spoken language of the masses. It has no fixed origin.

When a boat (especially a non-motorized boat) is lying sideways, it will be deflected when it is impacted by the force of a large area of ????water. The force it receives is along the direction of the water flow. But in most river sections, the water flow is The flow direction changes with the topography of the river bed, so it is difficult for ships to control the state.

In the "bridge gate", which is the bridge hole, due to the existence of the bridge piers and the width of the bridge, the water flow will form a straight forward state as if passing through the bridge hole when passing through the bridge hole.

And due to the diversion effect of the bridge piers, the water flow will naturally converge towards the bridge opening before entering the bridge opening. In this way, even if the ship could not be controlled well before, as long as the ship drifts in front of the bridge, it will maintain a straight and stable state due to the special topography of the bridge tunnel.

The boat will naturally go straight when it reaches the bridge. This means that the winding river channel may seem impossible to pass under the bridge, but when you get there, you will find that the boat will naturally pass perpendicular to the bridge. This means that there is no need to worry beforehand, the problem can always be solved by then.

If you know how to hold back when you have more time behind you, why would you want to look back (too late) when you are at the end of your rope? A Western philosopher once said: "When God closes a door, he will open another window." This is in line with the ancient saying, "When a car reaches the mountain, there must be a road, and when a boat reaches the bridge, it will naturally go straight."

Lu You also has a similar theme in the poem "Visiting Shanxi Village": "There are mountains and rivers, and there is no way, and there is another village with dark willows and bright flowers." He first mentioned the barriers of thousands of mountains and rivers, which seemed to have fallen.
