Tek-Sing, China's Titanic

The South China Sea is a fabulous hunting ground for treasure hunters. In the 18th and 19th centuries a stream of trading ships from Holland and England, and huge ocean going junks from China, criss crossed these seas, carrying countless treasures from the Orient. This unique programme tells the remarkable story of the search for the Tek Sing, a Chinese junk which sank in 1822 on the Belvidere Reef in the South China Sea with the loss of nearly 2000 lives and its valuable cargo.
