Wangtan Bridge, with its winding structure, is an ideal place to enjoy the scenery of Jingyue Lake with distant mountains and close water. Changchun Jingyue Lake and Taiwan Sun Moon Lake are sister lakes to each other. In August 2007, the "Jingyue Lake · Sun Moon Lake" pool water integration ceremony was held at Wangtan Square. Taiwanese high school students, with the blessings of their compatriots, injected the Sun Moon Lake water into Jingyue Lake and brought it back to Taiwan to integrate into the Sun Moon Lake. The two bays and pools of water have promoted friendly exchanges between the people on both sides of the Taiwan Strait, connecting the inseparable friendship between the two sides. It can be said that "two dreams come true in two places, and a bottle of water has a heart full of meaning". Nowadays, there is a cruise ship called "Sun Moon Lake" in Jingyue Lake, and there is also a cruise ship called "Jingyue Lake" in the same area.
