Wuxi Mekong Island is located by Taihu Lake. Mekong Island is named after Zhang Yu, the sage of the water in Wuxi area of the Han Dynasty. Legend has it that because of his governance, the water flow of Wuhu and Taihu Lake is smooth, and Wuxi has become a rich land of fish and rice in the south of the Yangtze River. Therefore, there is a custom of worshipping Zhang Yu on the eighth day of February of the lunar calendar.
