The Changguangxi wetland, dubbed "the lung of Taiku and Lihu lakes" in Wuxi, is gorgeously vibrant, decorated with lush rape flowers.

The Changguangxi wetland, at the foot of Junzhang Hill, is 10 kilometers long and covers an area of about 260 hectares, including a water area of about 80 hectares.

It was a canal dug during the Three Kingdom period (AD220-280) connecting Lihu Lake to the north and Taihu Lake to the south, and is now one of ten national urban wetland parks in China.

The Shitang Bridge in the park is one of the landmarks of the East Lihu Lake scenic area. It is the longest lounge bridge in Wuxi, representing the history and culture of the Lihu Lake and the characteristics of the Yangtze River.
