As a key project of the Zhejiang Nanxun parallel session of the 24th China Shanghai International Arts Festival, the Nanxun International Children’s Cultural and Arts Season ushered in a comprehensive upgrade to its “Version 3.0”. Adopting the theme “Embracing Family, Creating Without Borders”,it featured a diverse range of activities including lawn performances, ancient town parades, and markets, and art installations. Over three weekends, it presented 6 large-scale outdoor lawn performances and over 150 carnival parades in the ancient town, creating an immersive cultural feast for parent-child families in the Yangtze River Delta. Through resource integration and cultural co-creation, the Arts Festival and its parallel session have carried forward the heritage of Jiangnan culture and further promoted international cultural exchange and cooperation.
