Unsurprisingly, concern for the local environment informs the festival programming to a large extent. In 2023, Hui led the Peng Chau Rocky Shore Tour, which was meant to familiarize participants with the dynamic relationships between tides, coastal environments, and diverse organisms inhabiting the interisland area.

"I always think it is important to document the biodiversity around us," Hui says, adding that he would like participants to take away "some basic understanding of the local ecosystem and species" from the experience. "I think I can contribute to the festival by raising awareness of the coastal system around us," he says.
