At the 2023 Shanghai Xintiandi Design Festival, LZA's creation, "Formlessness," was exhibited at Xintiandi Plaza from May 31 to June 25. The art installation is inspired by Chapter 14 of Laozi's Tao Te Ching and explores the existence that cannot be perceived. By showcasing the void and substances that lack physical form, it presents an existence that is intangible yet real, stimulating the perceptions of viewers, guiding them beyond the material world to explore deeper existence and meaning. The fluid lines and changing light and shadow effects of "Formlessness" have a strong artistic appeal, allowing for abstract artistic imagination. It can also serve as a leisure and entertainment space for city residents, where people can rest, socialize, and enjoy life, bringing positive impacts to the city in multiple aspects.
