As the need for balancing cultural heritage preservation with economic development becomes increasingly urgent, the sustainable development of ancient villages has emerged as a critical issue. This study focuses on the ancient villages of Tengchong, Yunnan, to examine the profound impact of art intervention in public spaces on their development.
