Huai'an water system is developed, and there are Li Canal, Ancient Huaihe River, Hongze Lake and so on in the area. This is my second time to Huai'an. I have been to Zhou Enlai's former residence, Wu Chengen's former residence, and Hexia Ancient Town in the past few years. This time, I went to the attractions related to these water systems, including the Sapporo Transport Museum, the Governor Sapporo Transportation Office, the Lihe Cultural Corridor, Hongze Lake Ancient Temple, etc., which are all of great value for viewing.
