The Main River is a tributary of the Rhine River and the mother river of Frankfurt. There is an iron bridge over the river, covered with concentric locks symbolizing love vows. Walking on the bridge, watching the river slowly flowing, listening to the melodious accordion sound coming from the ear, you will have the feeling of people on the journey. This trip is also to meet a wish, has been to Europe several times, but has not touched the classics worth seeing. Although a little in a hurry, but a lot less cumbersome, want to leave, but also a lot of convenience. This is the first scenic spot to arrive at the destination and leave a perfect impression.
