The Development Bureau and Drainage Services Department initiated the "Revitalization of Tsui Ping River" project in 2020 and, completed it in 2024. The project transformed the 1-kilometer-long concrete nullah into a riverfront public open space with flood prevention, ecological, and recreational functions. The project included deepening the riverbed, installing the smart water gate to manage water levels, and integrating landscaping, greening, and ecological improvements, turning the nullah into a vibrant river and a new green landmark in East Kowloon.
