A city and a bridge. Thousands of hours, thousands of years to the waves of the river alone, a song of Huilan Flying Rainbow, two cities sleeping in the rain and smoke Changhong. At that time, it was a rainbow bridge connecting the ancient city of Yuyao to the north and south. Now, it is called the first bridge in eastern Zhejiang because it is the longest and tallest three-hole bridge on the Yao River. The north of the bridge is a busy commercial street. And the two ancient city walls, there is only a little bit of Shunjiang downstairs.
