The joyous Spring Festival is drawing to a close. During this Spring Festival holiday, cultural and tourism scenic spots across the country are all in a booming state. Wazi Street in Shanghang, Fujian, has also welcomed a peak of Spring Festival tourists. Moreover, this Spring Festival, Wazi Street has brought a brand-new cultural and tourism experience to numerous tourists. During the Spring Festival in 2025, the Tongxin Square on Wazi Street in Shanghang, Fujian, witnessed a collision between technology and culture amidst the traditional festive atmosphere. When night falls, lights and shadows flow on the square. Tourists step on the "auspicious cloud" patterns of the interactive projection and play with the fireworks and koi carps on the ground. Elsewhere, the cultural and tourism promotional video of Shanghang showcases Hakka culture, red history, and the beautiful scenery of mountains and rivers with a stunning projection effect. This cultural and tourism light and shadow feast, painstakingly created by Diheng Co., Ltd. for its clients, not only adds a joyful atmosphere to the New Year but also interprets the new possibilities of the integration of culture and tourism with innovative technologies. And behind this cultural and tourism light and shadow feast, there are its heroes, namely, Diheng's agent partners.  

When tourists step on it, the projected images respond in real time: carps leap out of the water, fireworks burst with every step, and the lanterns with the Chinese character "Fu" (meaning good fortune) slowly rise... This immersive interaction not only attracts children to frolic but also makes the elders exclaim that "technology makes the Spring Festival atmosphere even stronger."  

"The project delivery period coincided with the Spring Festival, and the overall project duration, including aspects such as scheme design, construction, and debugging, from scratch to completion, was only 14 days in total. Our agents were in a race against time, and at such a time, we needed to provide even better service. Moreover, many people who have worked on projects know that there are numerous unexpected situations in a project. During the Spring Festival, we were faced with issues such as a tight delivery schedule, suspended logistics, and a shortage of labor. It was indeed a very difficult task. However, we gritted our teeth and worked together with the agents, and finally managed to deliver a perfect result," said Manager Du of Diheng, the person in charge of the project. From equipment debugging to scene adaptation, he provided support to the agent team and worked continuously for several days and nights during the Spring Festival. Due to the special nature of the project site, with a large number of tourists during the day, the equipment debugging and installation work could only be carried out at night. Manager Du, the customer manager of Diheng, and the agent team worked from late at night until early morning for several consecutive nights during the Spring Festival. In order to ensure the perfect presentation of every light and shadow detail, they worked until four or five o'clock in the morning every day, and sometimes even stayed up all night. During the implementation of the project, the leaders of Shanghang's cultural and tourism department paid several visits to offer their regards at night, which undoubtedly gave us great confidence to present the project perfectly. As the saying goes, hard work pays off. Finally, one day before New Year's Eve, Diheng's service agents completed the project, allowing everyone to heave a sigh of relief.  

Manager Du said, "The temperature is low at night, and the on-site conditions are quite complex. However, we must overcome these difficulties. In the installation, debugging, and calibration of the equipment, not the slightest bit of carelessness is allowed in every single step." In the cold winter nights, the technical team debugged the projections over and over again, tested the response speed of the interaction, and optimized the visual effects of the images to ensure that tourists could enjoy the best light and shadow experience the next day. When they encountered problems that were difficult to solve late at night or in the early morning, the technicians of Diheng also provided remote support to our agents to help them resolve these issues.  

"Customer satisfaction is our New Year's gift." Manager Du's words are a microcosm of Diheng's "customer first" philosophy. This spirit of professionalism is not only reflected in Manager Du but also permeates the entire Diheng team. They have demonstrated with practical actions the service concept of "customer-centricity" and also showcased Diheng's responsibility and commitment as a national brand.

For the ground interactive projection in the center of the square in this project, Diheng's DU21K laser projector was used. Through the built-in geometric correction technology and built-in fusion function, it can flexibly adjust the 17*17 grid points, perfectly adapting to the irregular ground and achieving seamless splicing of multiple laser projections. The DU21K is renowned for its high brightness, high color restoration degree, and stable performance. It can still maintain excellent image quality performance even in complex lighting environments. Its built-in intelligent temperature control system and fully sealed optical design ensure the stability of the equipment during long-term operation. Even on cold winter nights, it can continuously provide tourists with a smooth interactive experience.

The light and shadow project at the Tongxin Square on Wazi Street in Shanghang this time not only added fun to the New Year but also contributed to the development of cultural tourism in Shanghang. Through the combination of ground interactive projection and cultural tourism promotional videos, tourists can more intuitively feel the cultural heritage and natural scenery of Shanghang while having fun. This innovative form of cultural tourism breaks the single traditional tourism model, enabling tourists to understand Shanghang through interaction and fall in love with Shanghang in the light and shadow.

Through the "light and shadow + cultural tourism" model, Diheng helps local cultural tourism transform from "check-in tourism" to "immersive experience", achieving a win-win situation between cultural dissemination and economic benefits. During this Spring Festival, the light and shadow feast at the Tongxin Square on Wazi Street in Shanghang made tourists remember the warmth of technology and the profoundness of culture. And Diheng Co., Ltd. is fulfilling its original aspiration of "creating a world-class national brand" with every technological breakthrough and every commitment to its customers.
