This long-term project is dedicated to preserving the biodiversity of Old Tea Forests of the Jingmai Mountain—a UNESCO World Heritage site—and the traditional food ingredients of the Blang ethnic group. Located in southwestern China, Jingmai Mountain is not only a unique rainforest ecosystem but also a profound fusion of ethnic traditions and ecological wisdom. The ancient tea forests employ a "shade-grown tea" model, which contrasts with the large-scale terrace tea plantations. This approach integrates ecological ethics with traditional agricultural knowledge, offering a sustainable land-use model that promotes harmonious coexistence with nature. However, the rapid expansion of tourism and the acceleration of economic modernization have led to ecological degradation, loss of biodiversity, weakening of cultural traditions, and economic monoculture in the region.

Spanning several art and design disciplines, the project combines design research, participatory art dinners, documentary film making, and ecological recipe design in an experimental exploration. The core components—"Food Feast", "Food Currency", and "Food Memories"— highlight the harmonious relationship between the Blang people and the ancient tea forests, presenting a forward-thinking design approach to ecological civilization. "Food Feast" invites three generations of the Blang people to exchange ideas of tradition and innovation; "Food Currency" connects urban and rural areas through tea-centred ecological recipes and toolkits, deepening awareness of ecological diversity; while "Food Memories" records the project’s journey, creating an ecological ethnographic archive of Jingmai Mountain.
