In 1950, it was designated as a leper colony, and the islanders were relocated to Tai Pak, Shap Long and Cheung Chau. In 1954, leprosarium was established through a collaboration between the Leprosy Mission London and the Hong Kong Government. The facility reach its peak in the early 1960s, housing as many as 540 patients. In 1974, the leper colony was closed, and the remaining patients were relocated to the newly established Lai Chi Kok Hospital. Following the closure of the colony, the island was repurposed by the Correctional Services Department.
In recognition of the island's new purpose, the island was renamed to Hei Ling Chau, which translates to "Island of Joyful Healing".
