The Brothers or Mo To Chau (Chinese: 磨刀洲, or 大小磨刀洲) consist of two islands in Hong Kong, Siu Mo To (or East Brother, 小磨刀洲) and Tai Mo To (or West Brother, 大磨刀洲). The two islands have been leveled to avoid affecting aviation of the nearby Hong Kong International Airport. Administratively, they are under the jurisdiction of Tuen Mun District.
