gdm Hong Kong presents the first solo exhibition in Greater China of Tang Chang (1934–1990), curated by art historian Sheryl Gwee—reframing the Sino-Thai poet and painter’s lively visions of being in the world through classical philosophy and aesthetics. Into the Heart-Mind invites us to see Tang Chang not as a peripheral figure, but as one of Asia’s most radical self-taught artists—his work leaps across the limits of language, across space and time, traversing worlds to meet us in the here and now.Tang Chang was never taught to paint. He was a self-taught visionary who moved fluidly between languages and cultures—yet never left the city of his birth. Born to a Chinese immigrant family in Bangkok, he translated the Daodejing and Shitao’s Treatise on Painting into Thai, while walking the same alleyways and sun-drenched fields for decades. Beyond mere eccentricity, Tang Chang’s free play with pictorial elements traces a dynamic  mode of presence. His fingertip, nails, brushes and pens move as one. Writing and painting collapse into each other. The Thai words for dharma (ธรรม) and dao (เต๋า) multiply across the page,   both naming and embodying the rhythm of life itself. His works are not just depictions of place but reflection  of consciousness—mirror-images of a heart-mind in constant dialogue with the world.Organized into four thematic strands—True Forms, Writing the Cosmos, Wilderness Colors, Living Traces—the exhibition traces how Tang Chang approached existence as aesthetic cultivation. From monochromatic ink studies that distil riverscapes into calligraphic gesture, to fluorescent fields where verve and vitality bleeds through layered washes of color and dragged fingerprints, to cosmic compositions where the order of heaven and the order of the heart become one.
