Tsz Wan Shan
The estate was formerly the site of Block 66 of Tsz Wan Shan Estate. The block was the largest in the estate. In 1980, the block was reassigned to Tsz Man Estate. In 1997, the block was demolished. In 2002, 5 new HOS blocks of Tsz On Court were completed in the site. However, they were finally transferred to public housing and renamed as Tsz Hong Estate.
