The whole bridge is using 260w laser beam. Strong penetration in the sky. The Tianmen Corridor has installed a music, light and water waterfall system on the circular corridor at an altitude of 500 meters, forming a large circular music waterfall with a total circumference of 168 meters. It not only gives tourists the feeling of "a waterfall falling 3,000 feet" during the day, but also allows tourists to enjoy the rainbow in the sky formed when the sun shines obliquely on the circular waterfall. At nightfall, as the lights of the circular music waterfall are turned on, the dynamic performance of more than 2,000 dazzling lamps merges into a wonderful light feast.
