Tung Chung (東涌), meaning ‘eastern stream’, is an area situated on the north-western coast of Lantau Island in Hong Kong. The area was once a major defense stronghold against pirates and foreign military during Ming and Qing dynasties. Since the Song Dynasty between 960–1279 AD, there have been people living in Tung Chung. At that time, they lived on fishing and agriculture. The place was originally called Tung Sai Chung, when Hong Kong was still a group of fishing villages. Tung means east in Cantonese, while Sai means west. At that time, merchandising ships sailed east to the village and west to Macau.
Tung Chung Valley is the home of some of the steepest and most primeval mountain streams in Hong Kong. The formation of spectacular waterfalls is facilitated in the presence of the sheer cliffs and deep gorges in the valley.
Being the main branch of the Tung Chung Valley, the deep-set Wong Lung Valley is the home of the Wong Lung Stream (The Yellow Dragon). The main stream has its source on the saddle at the east of Sunset Peak, but the stream collects water through a large network of feeder streams on both sides of the valley, including the famous Tung-Lung, Pak-Lung, Chong-Lung, and Ngo-Lung Streams, which are known collectively as “The Five Dragons of Tung Chung”.
We call it “Wong-Lung” (Yellow Dragon) since during a heavy rainstorm, when we view from the high ground, the stream resembles a yellow dragon ready to take off for heaven when it and its feeders are flooded with torrential muddy water, with Wong-Lung as the trunk and the feeders its limbs.
