With a history of over 320 years, the Yeung Hau Temple in Tai O carries the profound cultural customs of both land and water residents. Among its most significant traditions is the Tai O Dragon Boat Water Parade, which is inscribed on the national list of intangible cultural heritage. Through the Hau Wong Festival, the documentary presents the craftsmanship of bamboo-shed theatre and Cantonese opera performances, bearing witness to the enduring legacy of this intangible heritage and the unwavering perseverance of seven generations of the local community. The Craftsmanship of the "Three Treasures of Cha Chaan Teng" examines the techniques behind Hong Kong-style milk tea, pineapple buns, and egg tarts—three culinary treasures that have been officially inscribed on Hong Kong's intangible cultural heritage inventory, embodying a fusion of Eastern and Western cultures through taste and carrying the collective memory of the city's people.
