Butterfly Valley
As its (Chinese) name suggests , it was formerly a bay with a long sandy beach. It spans roughly from today's Butterfly Valley Road at the west to Yen Chow Street at the east. The beach was a gathering place for many Tanka fishermen before its development. The original shoreline approximates the present Castle Peak Road and Un Chau Street. Inland, villages of Om Yam, Ma Lung Hang, Pak Shu Lung, So Uk, Li Uk, Wong Uk and others sparsely occupied the whole bay of Cheung Sha Wan. Rivers from Beacon Hill, Crow's Nest and Piper's Hill formed a long plain behind the beach. Farmlands filled between villages. A larger river ran in Butterfly Valley separating Cheung Sha Wan and Lai Chi Kok. A sandbar was found at the mouth of its estuary.
