While Beijing has taken initial steps on tourism initiatives this winter, finding effective solutions to further stimulate urban vitality in the cold months and boost the night economy requires more exploration, he said.

However, light shows have a natural advantage in attracting people, Xiong said. Chasing a light source is embedded in the human psyche, with illumination giving people a sense of warmth and security.

"Fundamentally, a light show fulfills people's inner emotional needs for the pursuit of a better life and greater expectations," Xiong said.

This winter's light displays in Beijing had also gone beyond "illumination and beautification" to express the city's values and aspirations, he added.

"The light show was by no means a mere display of high-tech skills. It integrated design with the urban landscape and cultural roots to resonate with the visitors," he said.
