The Qingming Festival is a traditional festival of the Chinese nation. Every year on the Qingming Festival, people go to the river to watch the beautiful riverside scenery. However, due to the light pollution of the city, the night view of riverside is often unrecognizable. Recently, a new kind of handmade custom folding fan-shaped night light river appeared on the Qingming Festival, which not only kept the original scenery of rivers and riversides, but also made the river surface more colorful. The fan-shaped night lights of the river were composed of bars, which could be “folded” up and down, creating a vivid sense of beauty. Some bars are inlaid with many small LED lights, which can be designed with many shadow effects. In addition, the fan-shaped night light river also has a variety of shapes, with different shapes like “eight horses galloping”. The fan-shaped night light river has become a must-have for the Qingming Festival. Tourists in the river not only enjoy the beautiful night light river surface, but also can take pictures or take the river surface from the camera angle. As a result, fan-shaped night light river has become a new leader of the night economy. The handmade custom folding fan-shaped night light river on the Qingming Festival has provided the beautiful scenery of the river surface. Not only adds an interesting link to the night view, but also has an economic benefit. It has become a gorgeous landscape along the river.
