Wang Xuefeng is a Professor and Master's Supervisor at Guangxi Arts University, China. He specialises in employing innovative techniques in blue-green landscape painting to depict the landscapes of southern China and its ethnic minorities. His landscape painting "Sunny Day" centres on the "Houses on Rocks" at Yuanbaoshan Qingzhai Village in Rongshui Miao Autonomous County, Guangxi, China. Blending traditional ink wash with mineral pigments, it conveys local ecology and ethnic culture through on-site sketching. This article examines the work through a semiotic lens, integrating ecological aesthetics theory to analyse its symbolic expression of rural sentiment. Taking Yuanbaoshan's "Stone-Top Dwellings" as its geographical prototype, "Sunny Day" translates the Miao people's survival logic of "living by mountains and waters" through visual forms of objects. It employs colour-emotion coding to bear the collective memory and cultural identity of the ethnic group, while conveying the triple dimensions of "ecology-life-spirit" in the countryside through compositional order. This achieves an emotional elevation from concrete geographical landscapes to humanity's "spiritual homeland," ultimately becoming an artistic vessel that safeguards rural authenticity and perpetuates cultural memory within an urbanised context. It offers reference points for the creation and interpretation of contemporary landscape paintings centred on rural themes.
