In the yards scattered around Kaohsiung harbor they still build junks for the fishing fleets that are direct, recognizable descendants of the ships that formed Cheng Ho’s armadas. You can take a short ferry ride from the shipbreakers’ piers, where vessels of modern vintage are being put to death, to places, such as Chichin Island, where junks of the ancient lineage are being given birth.

In the 1980s, Chichin Island could only be reached by boat and was devoid of cars. The mayor of Kaohsiung at that time proposed making this island into 'another Miami Beach'. It was not to be. Construction of the cross-harbour tunnel in 1985 has turned most of Chichin Island into a container port.

A bus stop cuts a lonely figure against the landscape of Dongsha Island. Although the sign identifies it as a Kaohsiung City bus stop, and the official address is part of Kaohsiung's Chichin district, Dongsha Island lies in the South China Sea, about 444km southwest of the city, and is part of the Pratas Islands.

Due to geographic restrictions prior to 1983, the development of the Port of Kaohsiung was limited to the northeast bank of the fairway. The Chichin District, on the southwest bank, was largely sidestepped by construction of the No. 2 Entrance in 1969. The port reopened the Chung-Hsin Commercial Harbor Area as Container Terminal No. 4 in 1983 in order to facilitate equitable harbor development on both sides of the main fairway, improve overall utilization of port land, attract more container shipping business, and expand services available to shipping customers.To end Chichin’s isolation and increase the accessibility of all port land, a Cross-Harbor Tunnel was completed 3 years ahead of the completion of the Container Terminal No. 4 project. The tunnel was designed to serve the needs of both container traffic and Chichin District residents.
