During the May Day holiday, the 2023 Changqin Island Mango Music Season May Day Island Special was held on Changqin Island in Zhuhai, marking the official opening of the country's first uninhabited island development project to the public.

It is understood that Changqin Island is a key marine industry project in Zhuhai City and the first "public welfare+tourism" uninhabited island development project in China. The area is called Triangle Island, with a total land area of 0.87 square kilometers. It is constructed and operated by Zhuhai Jiuzhou Holdings Group. Since obtaining the development and use rights in 2017, Changqin Island has continuously promoted the ecological restoration of marine islands and deeply integrated the development of music and cultural resources. It is committed to creating an island tourism complex that integrates music culture, popular science education, themed experiences, sea sports, and leisure vacation, as well as a fashionable cultural tourism destination in the Guangdong Hong Kong Macao Greater Bay Area.
