The "Bridge within a Bridge" is a scenic attraction created by two ancient bridges, the Tongji Bridge which crosses the river from east to west and the Renji Bridge running from south to north that joins the former at one end. Either of two bridges can be seen through the arch of the other, hence the name.

Having been rebuilt five times, Tongji Bridge is a 28.4 metres (93 ft) and 3.5 metres (11 ft) one-curvature arch bridge, with a span of 11.8 metres (39 ft). Renji Bridge, which has also undergone repairs during its history, has a length of 22.6 metres (74 ft), a width of 2.8 metres (9.2 ft) and a span of 8.5 metres (28 ft).

Demonstration in the traditional workshops district display traditional crafts as the printing and dyeing of blue printed fabrics, the primitive techniques of cloth shoe making and tobacco-planing. Visitors may operate the machines to get an idea of how the original work was carried out over 200 years ago. The local houses here are decorated with carved wooden and stone doors and windows.
