Yu Garden is the largest of Shanghai's ancient gardens with Ming and Qing architectural styles. Yu Garden is small in size, but it contains all elements that a classical Chinese garden should have. The pavilions, halls, rockeries, ponds and cloisters all have unique characteristics. The garden has six areas, each with its own style. The Grand Rockery, in the center of the Garden, is the most renowned sight. You can walk to the Zigzag Nine Bend Bridge. Chinese people believe that the number nine symbolizes auspiciousness. Walking across the Bridge is said to bring people good luck. The Bridge leads to Mid-Lake Pavilion Teahouse, which is the oldest teahouse in Shanghai.
