Wangtan Bridge is there. The bridge body meanders from the mountains to the water, and is the ideal place to see the scenery of Jingyuetan. Changchun Jingyuetan and Taiwan's Sun Moon Lake are sister pools. In August 2007, at Wangtan Square held a "Jingyuetan - Sun Moon Lake" pool water integration ceremony. Taiwan's high school students, with the blessing of the people of Taiwan Province, poured the Sun Moon Lake water into the Jingyuetan, and in turn, brought back the water of the Jingyuetan to the Sun Moon Lake on the island of Taiwan. The two pools of water promote the friendly exchanges between the people on both sides of the Taiwan Strait, connecting the people on both sides of the Taiwan Strait to cut the bonds of friendship, which can be said to be "wave traces of the two dreams to fulfill their dreams, a bottle of water meaning the heart of the heart". Nowadays, there is a cruise ship named "Sun Moon Lake" in Jingyuetan, and there is also a cruise ship named "Jingyuetan" in Sun Moon Lake.
