Tung Wah Hospital
While the boundaries are not "de jure" drawn, they are nevertheless "de facto" defined by Whitty Street in the west and Tung Wah Hospital in the east. The HKU MTR station exit B1 straddles the boundary between Shek Tong Tsui and Sai Ying Pun. Good Luck Mansion and The Kadoorie Biological Sciences Building are in Shek Tong Tsui, while Saint Anthony's Church, Pao Siu Loong Building, and the Main Building are in Sai Ying Pun.
