Germany under William II was eager to become one of the superpowers in the world. In 1897, Germany occupied China's Jiaozhou (Kiautschou) Bay, and established an imperial government to control this "Schutzgebiet". Kiautschou became the showroom of Germany's technology, cultural achievement and prestige in the international world. It was also the arena for the Royal Navy to display its strength. The harbor and railroad were thus constructed, as well as the water supply and sewerage systems, clinic and hospitals. However, all these facilities were primarily available to the Europeans in Kiautschou. As for the Chinese, the imperial government remained passive and inclined to adopt only preventive measures against outbreak of epidemic. On the other hand it also adopted new regulations and punishments to prevent the Chinese from any law-breaking behavior, as usual. The colonial government's policies concerning hygienic facilities in Kiautschou not only exemplify its peculiarity, they also reflects the common attributes of colonial system.
