Pak Chai is active in the realms of contemporary art and applied social sciences. In 2024, he created “The Life Atlas of Chuen Lung’s Man Jai” for Koon Man Space, based on the oral history of local villager “Man Jai”. He also compiled “The Chuen Lung Dictionary,” a record of Chuen Lung’s cultural traditions and the history of its people. In capturing authentic moments, portrait photography conveys a poetic beauty. Pak Chai will photograph portraits of Chuen Lung villagers, and these images not only showcase their faces and postures but also use the interplay of light, shadow, and settings to emphasize the weight of historical currents in the 1960s and 1970s. From these works, he outlines and synthesizes the rhythms of life and cultural essence from the past century, inviting viewers to reflect on the intricate connections between modern social structures and historical culture.
