At dusk, dots of light and shadow danced on the bluestone road of the Old Street of Liuba County Hall, Hanzhong City, Shaanxi Province. Seven or eight children chased the rolling football on the ground, and their childish laughter awakened the sleeping eaves and brackets.

This light and shadow adventure originated from the lighting and beautification project implemented by Zibai Subdistrict Office. Walking along the old street, the "Hundred Family Names Lantern Corridor" came into view, with surnames such as Wang, Li, and Zhang flowing in the warm yellow halo. When tourist Mr. Chen looked up to find his own surname, "Finding my own surname here seems to have a wonderful connection with the old street, and the experience is particularly special." Mr. Chen said.

The projection landscape of poetry and culture is also eye-catching. On the walls of the old street, classic poems and beautiful pictures complement each other. As night falls and the projection starts, Li Bai's bold poems are matched with magnificent mountains and rivers, and Du Fu's melancholy works are integrated into historical scenes. The picture slowly unfolds, and many tourists stop to recite, immersed in the rich cultural atmosphere.

The most popular area is the laser interactive projection area. Gently stamp your feet, colorful flowers bloom on the ground, ginkgo leaves scatter with your footsteps, children laugh and run, and adults are also attracted by the novel experience, and they all participate and raise their mobile phones to record this dreamy moment.

"Now the street lights will 'bloom', and the children are reluctant to go home after school. They often come here to have fun. Tourists also think it is very good and creative. When the tourist season comes, there will definitely be more people, and this year's business will be better." Yang Weihong, a merchant in the old street, pointed to the ground projection in front of the store and said.

"This lighting and beautification has given the old street a new look, adding an ancient cultural atmosphere, a sense of technology and fashion, and creating an immersive interactive experience scene for tourists and citizens, which has enhanced the old street's appearance, temperament and warmth, and laid the foundation for the next step of lighting up the old street's night economy." Tang Qi, director of the People's Armed Forces Department of Zibai Sub-district Office, said.

It is reported that in order to preserve the original style of the old street to the greatest extent and create a warm and peaceful atmosphere, this project uses soft warm-toned lights such as yellow light to create a total of 6 landscapes such as the "Hundred Family Names Lantern Corridor", the poetry and culture projection wall, and the laser interactive "scene roaming", which together outline the beautiful night scene of the old street.

As the lights come on, the laser under the archway of the old street projects the words "Liuba, please stay". At this moment, the old street is not only a children's corridor where children chase and play, but also a theater for tourists to pursue their dreams, and a museum where traditional culture and modern technology dialogue. Every lamp tells the story of Liuba's changes from ancient times to the present, and every beam of light is weaving the future picture of the mountain city. The Qinling "reception hall" business card is becoming more and more shining, and Liuba County is welcoming visitors from all directions with a brand new attitude.
