西環
The current perimeter of Siu Sai Wan includes the rest of Chai Wan east of Wing Tai Road. Prior to reclamation, Siu Sai Wan was a small bay east of Chai Wan. Chai Wan was once known as "Sai Wan" (; "West Bay"), and the small bay as Siu Chai Wan (; "Small Chai Wan") or Chai Wan Tsai (; "Little Chai Wan"), and over time the names combined into the current name Siu Sai Wan.
